BATHROOMS or whatever you call them, as they have many names – are a necessary part of our lives, but we often take them for granted. Bathrooms did not always exist as a dedicated room, and the conglomeration of fixtures and practices that occur in these rooms today, as well as the design of these rooms, are a result of many societal and technological changes. Understanding the history can help you better appreciate (or create) your own historic or period appropriate bathroom.

Bathrooms: History and Evolution

Bathing and specific elimination practices (e.g., toileting) have been around in some form since humans have existed on Earth. However, more sophisticated practices – including devoted bath houses and use of bathtubs – began as early as 3000 B.C. in what is now Pakistan, with the Indus Valley Civilization, and continued with the early Greeks and Romans. In those times, people focused on purity but not necessarily health and hygiene, and water was seen as a cleansing element for spiritual and physical purposes. So powerful was the belief in water’s protective spiritual properties that communal baths were sometimes kept separate from domestic living spaces to protect the living spaces from evil spirits. The Romans especially valued bathing as a way to relax and revive themselves, as well as an outlet to commune with others. However, the wealthy also often had private bath spaces. (Source). 

The oldest-surviving bathtub dates to 1700 B.C. and was located in a palace in Crete. (Source).

In ancient times there were also some primitive flushing toilets, although many public toilets in Rome were anything but private and did not necessarily flush. (Source). 

In addition to limited private toilets, many ancient Romans were relegated to using primitive, communal items before the invention of toilet paper. (Source). 

In the Middle Ages, public bathhouses continued to be used, and soap first came into production. Other items such as combs, tweezers, and mouthwash were also in use. (Source). 

Contrary to popular belief, people in the Middle Ages valued bathing, particularly steam baths. Baths were generally public baths and men and women communed together; although, women covered their hair for “decency.” (Source)

During the Renaissance, private bathrooms became more popular. However, fears increased about disease, associated with water, and bathing was discouraged in favor of focused washing. Clean linens were thought to be sufficient to pull toxins from, cleanse, and deodorize the body, and women during this time toiled over washing. (Source). 

In 1546, King Henry VIII ordered the closure of public bathhouses, as these – specifically, their water – were blamed for the 7 plagues that occurred in England over a 200-year span. (Source).

Public toilets were used by the lower classes in the Renaissance and often placed on bridges over rivers, the “sewage system” being that debris would float away in the river. In the countryside and in some private city homes privies existed in sheds or cellars, usually consisting of seats situated over cesspits. Portable chamber pots were the preferred means of elimination by the wealthy and royal, and were simply emptied into the streets. (Source). 

The first flush toilet was invented by Sir John Harrington in 1596, but was not widespread until nearly 3 decades later –  the wealthy and royal preferred chamber pots be brought to them, and not to walk to a room only for toileting as it would be considered immodest. (Source). 

By the 18th century, daily bathing was still uncommon. However, in England the wealthy were able to have taps put into their homes allowing for private bathing, thanks to a massive irrigation project. Otherwise, most of the bathroom rituals we use today were still done in the bedroom, which usually included a basin and washstand (and often a chamber pot). (Source). 

The shower was invented by William Feetham in 1767. (Source).

By the 19th century, houses were beginning to be designed around usefulness of each room. The discovery and dissemination of information about germs and hygiene was more widespread in Europe and America, and many homes of the middle and upper class had bathrooms – as bathing was considered necessary for good hygiene – while mass showers existed for the poor. The Industrial Revolution also facilitated  mechanization in the bathroom, including gas water heaters for hot-water production. (Source). 

The 19th century saw major changes in private bathrooms in the home, including flush toilets in the 1850’s, and the electric water heater in 1889. (Source). 

In the late 19th century more was discovered about infectious disease and bacteria, and previously wooden bathrooms transitioned to porcelain and enamel surfaces, with more exposed pipes that were “easier to clean,” tile and linoleum replaced wood floors, and drapery was significantly reduced, and this continued into the early 20th century. (Source). 

The late 19th and early 20th century’s concerns about disease also resulted in the introduction of second bathrooms – “powder rooms” – or half-baths often on the first floor, near the entrance, so delivery people could wash their hands and prevent bringing germs into the home. (Source). 

As the 20th century moved beyond the hygiene movement, and the public was exposed to two world wars, glamorized interiors featured in movies, and a greater increase in population and technological advancement, people were more interested in having fully-equipped bathrooms that served functional needs as well as offered respite. The growing middle class was also able to afford these luxuries with mass-production enabling affordable products. (Source). 

The 1950’s realized en suite bathrooms, as well as separate bathrooms for the children. (Source)

As people have continued to associate bathrooms with comfort and escapism, the number of bathrooms per person in each household have steadily increased, and bathrooms continue to be an important part of each household. (Source). 

 

Bathrooms in Your Historic Home

If luck is on your side, you may acquire a historic home with a period bathroom still in place, although this is rare given that bathrooms (and kitchens) usually were the first “victims” of updates to historic homes, and are some of the most modified and modernized rooms. Depending on the old bathroom’s condition, there may be significant work to do. Because of the last few decades’ emphasis on college education and continued focus on mass-produced items that are generally not repairable and have short shelf-life, skilled labor and trades people have dwindled, so repair may be more difficult. However, increased demand for historic features has also resulted in more reproduction options available, many of which are up-to-code. Sometimes it is necessary or preferred to create a new bathroom, either modern or styled to a chosen time in the house’s history. Regardless, it is important to always remember that water is the enemy of a historic home, and any modern updates must account for this. Below are a combination of suggestions from Restoring Old Houses by Nigel Hutchins, and Restoring Your Historic House by Scott T. Hanson

It is important to remember that water is the enemy of historic homes, so all plumbing should be in good condition and well-maintained to prevent water disasters.

 

Restoring an old bathroom. General period plumbing knowledge is important in old bathrooms. Many old homes have extant period plumbing fixtures and these were designed to be repairable – just be sure they are adapted to meet modern codes and standards. A knowledgeable plumber and flexible code officer can be helpful with this. (Hanson, p. 374). Old plumbing fixtures and features should be examined for breaks and other damage and replaced with copper or plastic where necessary; return traps and vent stacks should be cleared; worn gaskets and washers should be replaced; and entire systems should be flushed and pressure checked (Hutchins, p. 179). Some shops and companies specialize in repair of such fixtures (Hanson, p. 375).

If something is missing, beyond repair, or simply cannot be adapted to meet modern code requirements, it is recommended that you look for antiques (often through salvage, but again these must be adapted to modern codes), or options among the many reproductions on the market. It is highly recommended you compare the quality of the originals to the reproductions, and buy as high quality as you can afford. This will more likely prevent failure and subsequent disaster from burst pipes (Hanson, p. 376; Hutchins, p. 178).

Rural residents have even more unique circumstances, including utilizing wells for water sources and septic tanks for waste disposal. Hutchins (p. 179) recommends that people in the countryside check their old wells for rotten covers, bacteria in the water, and how well they refill. Many old wells cannot accommodate modern needs and new wells must be dug, which are expensive – it is recommended a homeowner budgets accordingly.

Antique toilets also need to meet modern standards, even if they are antique. Hanson (p. 374) notes that some communities have strict water ordinances, and toilets from times past were designed to use much more water to flush (and thus fully clear the bowl) than is allowed by modern code. In some cases, an extant toilet can be grandfathered in. In other instances modifications to the tank such as stacked bricks or a tank liner can decrease water – Hanson warns, however, that because of the original design, this decreased water may not be sufficient to clear the bowl. High tank toilets are generally more successful because of the additional velocity they allow water when it travels from tank to toilet. 

Antique sinks also generally require modification to meet modern standards. Sometimes, antique sinks and counter tops simply need cleaning; marble sinks and counter tops can be cleaned with paint cleaner and steel wool, although deeper stains may require fine sandpaper and muriatic acid (Hutchins, p. 179). Hanson (p. 374-375). Problems usually stem from the size of drain holes and the spacing of faucet holes. An old sink that is missing the 2-hole drain stem can present a conundrum, as salvaged parts may be hard to come by, and it does not match modern pieces. Sink bowls of various materials may have these holes widened to accommodate modern needs. If the traditionally-separate hot and cold faucets are missing, reproductions can convert the hot and cold into one, and still visually represent the original time period.If a required overflow drain is missing, modifications can be made to retain the antique bowl; Hanson recommends connecting the bowl to the above top with a gap in between, and putting a modern bowl below to catch overflow. This of course should always be checked with local code enforcers.

Period tubs or showers can often be restored with epoxies – or homeowners can purchase “new” antiques and restore those, if needed (Hutchins, p. 179). Similar adjustments may need to be made to the plumbing parts as were noted for sinks, above. 

  •  

Creating a new bathroom (period appropriate or not). Hutchins (p. 178) provides several general plumbing points when creating a bathroom space. He indicates that plumbing should not be run on exterior walls because of insulation difficulties, and sufficient venting is necessary for plumbing. He also states that other considerations should be made if converting a non-bathroom into a bathroom. For example, one must consider if there is enough head room for a shower, if ceiling beams below (if on an upper floor) will be impacted by plumbing pipes, and if the room has wood features, how those features will be treated to protect them from moisture penetration. 

Laundry features should also be considered. Although not inherently part of a bathroom in most cases, Hanson (p. 377) also points out that given most modern private homes have laundry areas or rooms, and many of these are now being moved from the basement level to first floors, caution is warranted to protect historic interiors. For example, Hanson notes that typically-cheap hoses often result in burst pipes and indoor flooding disasters. These issues can be prevented – or at least mitigated – by replacing cheap hoses with high-quality woven stainless steel washer hoses, and installing overflow trays with drains for added protection, according to Hanson. 

 

IN SUMMARY: 

Modern people may be less modest than people of the past, but the bathroom and related activities can still be a taboo subject for some. For others, it’s simply taken for granted. But we must remember how essential bathrooms are to our physical and mental health, hygiene, and relaxation. As such, it’s important to treat and maintain these spaces well, particularly to protect the integrity of our historic homes.

Preservation and sustainability. What does one have to do with the other? If we examine these terms more closely, we can see that older buildings are inherently “green” or sustainable because of “embodied energy” (all of the energy used to build the building that would need to be expended to build something else). In fact, the report from the National Trust for Historic Preservation “The greenest building” states:

“This study finds that it takes 10 to 80 years for a new building that is 30 percent more efficient than an average-performing existing building to overcome, through efficient operations, the negative climate change impacts related to the construction process.”

This statement about life cycle analysis indicates that the construction process is resource intensive (both in production and transportation of new materials and landfill debris – about 20%-25% of landfill waste is construction-related). Reusing an existing building is the ultimate recycling, so preservation and sustainability are often inextricably linked, and this link highlights the importance and value for sustainability inherent in preservation.

PRESERVATION’S LINK TO SUSTAINABILITY

Not surprisingly, both the preservation and the “green”/sustainable initiatives have significant common ground and can work in concert with one another. This is particularly relevant in light of concerns regarding climate change and major environmental concerns. The National Trust for Historic Preservation formed the Preservation Green Lab in 2009 to strengthen the connection between preservation and sustainability, and updated the name to The Research and Policy Lab in recognition of expanded needs. The National Trust for Historic Preservation has increased focus on climate change impacts on our heritage. There is also an International Climate Heritage Network to address the intersection of climate change and other environmental disasters on arts, culture, and heritage.

However, at times in the recent past, green and preservation agendas have been at odds and there has been a bias in the sustainable building field to start over with new buildings and materials, as pointed out by Tristan Roberts, and The Washington State Department of Archaeology and Historical Preservation’s (DAHP) Sustainability and Historic Preservation Executive Summary from 2011. The Whole Building Design Guide’s Historic Preservation Subcommittee (WBDG) notes that there has also been a stigma attached to preservation and it has been (often inaccurately) labeled as inefficient and requiring overwhelming or costly procedures to retrofit energy efficient systems into old systems. Additionally, Roberts reports that certain sustainable products that are made of recycled content or other sustainable materials may not be approved by the National Park Service’s Secretary of Interior’s Standards for Rehabilitation simply because they disrupt a building’s character-defining appearance. However, preservation and sustainability are far from being mutually exclusive. As Roberts reports:

“Both the environment and cultural heritage suffer when buildings are treated as disposable.”

Below, we outline characteristics of preservation that lend themselves to sustainability:

  • Energy Efficiency. As noted earlier, it also takes less energy to maintain or rehabilitate an existing building than to demolish an existing building to construct a new building, even if that new building is “green.” Restoration involves less carbon emissions than new construction. Comparatively, DAHP noted in 2011 that new buildings accounted for 40% of all extracted energy sources and 68% of all consumed energy per year. DAHP also cited the U.S. Department of Energy (DOE) who shared data indicating that “commercial buildings constructed before 1920 actually use less energy per square foot than buildings from any other decade up until 2000.” New buildings made of new materials means one must consume energy to both create and ship those materials, and this also contributes to carbon emissions. DAHP adds that many historical buildings were designed with “passive systems,” or systems that took advantage of things like natural light, ventilation, and solar orientation when electrically-powered options did not exist. These passive system characteristics are all inherently sustainable and meet the same “green” goals of the sustainability camp. You can read more of our articles on energy efficiency in our archives here

 

  • Durability and Waste. Preserving a historical building reduces consumption of materials, and retaining old material creates less construction landfill waste. Green buildings should have materials that are both durable and repairable, whether that green building is new or old. Many new green building products are durable, but not necessarily repairable (read our repair archives here). Additionally, to build a new building with new materials, you have to create and ship the resources (both of which take energy), and often they are placed on newly cleared land which takes energy but also may be removing resources such as forest or farmland. Rehabilitating an existing or historical building eliminates a lot of these issues. Even reusing durable, salvaged materials from buildings that are torn down keeps those materials out of landfills and provides green materials for another building. However, more wasteful decisions are perpetuated, as Roberts points out that the construction industry often falls prey to “short-term thinking,” focusing on what works in-the-moment and disregarding long-term outcomes. Despite these benefits of preserving or rehabilitating older buildings, there can be challenges related to durability and waste in older buildings. Roberts notes that not all older buildings were well-built with durable material or construction, so in some cases, building damage is not due to neglect or abuse, but the way the building was constructed (e.g., some buildings with structural steel that is corroded cost a lot to repair). Further, as more modern buildings age and qualify as “historic” each year, these sometimes less durably-built structures pose new challenges for both the preservation and sustainability movements.

 

“GREENING” YOUR HISTORICAL COMMUNITY, BUILDING, OR HOME

Several efforts at the international and national level have been highlighted here for increasing connections between preservation and sustainability. WBDG’s Historic Preservation Subcommittee adds several guidelines that marry LEED guidelines for “greening” existing buildings with processes that incorporate specialization for historical buildings (here). However, there are several things individuals in and building and homeowners can do as well. On a community scale, The National Trust for Historic Preservation includes information on helping preserve your community and designating a historic place. Below are tips for owners of older buildings and homes. These are based primarily on the framework provided by the National Trust for Historic Preservation’s Meghan White in “8 Ways to Green Your Historic House“, listed below, as well as information from other articles and our own expertise:

  1. Conduct an energy audit. Know where energy may be leaking. White states “A popular example is the blower door test. This test involves using a high-powered fan to take the air out of the building, which depressurizes the interior. The difference in air pressure is then measured with an air pressure gauge.” The pressure difference allows outside air to come into the building via openings, which reveals areas you’ll need to seal.  
  2. Don’t replace windows (or doors, or siding, etc.). As we’ve noted several times, a big misconception is that historical windows are to blame for the drafts in homes. White reports “As the National Trust’s Research & Policy Lab (formerly known as the Preservation Green Lab) notes in their study Saving Windows, Saving Money, historic windows rarely deserve to be completely replaced. Instead, weatherstrip them or install minimally invasive storm windows so that they keep the drafts out and lower your energy bills. The study found that retrofitting windows are the most cost-efficient way to decrease a historic house’s carbon footprint. As a bonus, old growth wood found in historic windows lasts longer than modern day wood, so preserving your historic windows will keep you from having to replace them more often.” Similar points can be made for doors, siding, and many exterior home parts that separate the outside from the inside. DAHP adds that more energy is lost from plumbing openings and uninsulated ducts than windows. The key is to repair, restore, and maintain these protections from the outside elements.
  3. Insulate the attic and basement. White notes that energy escapes through uninsulated spots such as basements, crawl spaces, and attics. Insulating them can help to prevent air from escaping. They say “Cellulose is a great option because, unlike spray foam, it’s reversible.” They also caution “You should refrain from insulating walls because you’re removing the permeable vapor barrier inherent in historic structures. The walls of historic houses are made to breathe, but inhibiting movement of air and heat through and around the wall can lead to issues like trapped moisture.” This issue is closely related to our points about differences in modern mortar and historical mortar, and the inherent breathability of old wall materials. 
  4. Take advantage of your house’s natural passive heating and cooling. White says “Artificial cooling and heating methods can be some of the highest energy consumers in a historic house.” They suggest using your historical home’s shutters to cool your house naturally: open your windows and latch the shutters to allow natural air flow. The added bonus is it will shade your interior from the sun. Window awnings that are historically appropriate can also provide similar benefits. In cases where you want or need additional electric components, consider finding a preservation and sustainability-minded HVAC professional who can retrofit systems with little disturbance to your home’s historic fabric, as we discussed here
  5. Consider installing renewable energy sources. Installing solar, wind, or geothermal renewable energy sources on your historic property are also options to consider. White says “Solar panels produce electricity naturally and will help lower your bills. When connected to a utility power grid, modern wind turbines can also help create electricity using renewable resources and in a more cost-efficient manner. Read more about installing solar panels on historic properties here.” Tesla has also developed solar panels that are extremely sympathetic to the historical aesthetics of an older home, though it may be cost-prohibitive for many.
  6. Pay attention to your landscaping. Trees may help to conserve energy in your house,with deciduous trees providing shade in the summer and fallen leaves allowing sunlight to warm your house in late fall and winter. Another issue we acknowledge is environmental damage due to combined sewer systems in many cities. When it rains too much the system becomes overwhelmed and this causes untreated sewage to be dumped into streams and rivers and contaminates waterways. The EPA fines communities every time this happens. As an individual homeowner, you can prevent some of your own contribution to this problem by: creating a rain garden to divert the water away from the storm drain and also away from the foundation; installing permeable pavers laid in the traditional manner (with sand underneath instead of mortar); and you can build a drywell. Check with your local municipality to see if they have a grant to help defray the costs of to property owners who make these changes. 
  7. Change your Lightbulbs. White points out “According to the General Services Administration, High Efficiency Incandescent (HEI) lamps reduce energy by 50 to 75% and use only 25% of the energy that regular incandescent bulbs use. They also don’t alter the appearance of historic light fixtures where the bulbs are visible, like LEDs do. Otherwise, LEDs are a good option when the bulb is obscured by opaque shades or lenses.”
  8. Reuse old materials or salvage. White encourages readers renovating historical buildings to replace missing pieces with materials from salvage companies before resorting to all-new material. This helps preserve historical pieces and prevents some landfill waste. 
     

IN SUMMARY:

Preservation and sustainability have much in common, and destroying or demolishing old buildings is more wasteful than helpful, even when replacing it with a new “green building.” It is best to preserve what we do have, by repairing, restoring, and maintaining these buildings.
