Plus, we’ll even discuss practical tips for folks living in these vintage, one-bathroom homes. So, buckle up and get ready for a fun, enlightening dive into the past!

Historical Home Designs: A Blast from the Past

Ever wondered why older houses typically have only one bathroom? To get that, we need to rewind to a time when house designs were quite different.

Think simple, practical layouts serving everyday needs. Most homes had rooms for sleeping, eating, and hanging out. A dedicated room just for washing up? Not a common thing back then.

Smaller houses with fewer rooms were the norm in the 18th and 19th centuries. Central heating? Barely a thing.

So, small homes were practical and cozy. Plus, families were larger, often multi-generational. Fewer rooms serving multiple purposes was the way to go.

Why Just One Bathroom?

Now, let’s talk about bathrooms. The idea of a room specifically for personal hygiene is a pretty new thing.

Indoor plumbing became a common feature only in the late 19th and early 20th centuries. Before that, people made do with outhouses and chamber pots.

The idea of an indoor bathroom? Completely foreign. Once indoor plumbing became a thing, it was usually just one bathroom per house.


Simple. Plumbing was a luxury and pricey. So, one bathroom was the practical, economical choice.

Money, Society, and Culture: The Bathroom Influence

Why just one bathroom? The answer lies in a mix of economic, social, and cultural influences. Economically, installing plumbing wasn’t cheap.

Plus, many places didn’t have proper sewage systems until the mid to late 20th century.

Socially, families worked differently back then. Many things we do privately today were shared activities back in the day. So, one bathroom didn’t feel limiting, it felt normal.

Culturally, Victorian views on modesty didn’t push for multiple bathrooms. The bathroom was more function than comfort.

So, when we look at why older homes have one bathroom, it’s all about costs, plumbing being a luxury, societal norms, and cultural influences.

This combo shaped home designs and gave us the one-bathroom setup we often find in older homes.

Bathroom Evolution: From Luxury to Necessity

Old houses one bathroom

Let’s take a quick trip back in time to when indoor plumbing was cutting-edge tech. Believe it or not, the concept of a hygiene-dedicated room goes way back to ancient Rome and Greece.

They even had public bathhouses and some indoor plumbing! But after the Roman Empire fell, these innovations took a back seat in Europe for a long time.

Fast forward to mid to late 19th century America. That’s when indoor plumbing became more common, thanks to modern sewage systems.

This gave rise to the bathroom as we know it. But there’s a catch – only the rich could afford it.


Plumbing needed a water source, pipes, and a sewage or septic system. So, bathrooms started as a luxury for the wealthy.

Bathrooms: The Ultimate Luxury of the Past

Back in the day, if your house had a bathroom, you were doing pretty well. Bathrooms were signs of wealth, cleanliness, and civilization.

In a time when bathing wasn’t a daily ritual, having a dedicated space for it was a big deal.

Plus, indoor plumbing meant you could avoid trips to the outhouse, regardless of the weather.

Now, while this was a luxury, early bathrooms were basic, usually just a sink and tub, and the toilet in a separate space for privacy.

Then vs. Now: Bathroom Perceptions

Fast forward to today, and bathrooms are not just functional. They’re also spaces to relax and rejuvenate.

Think heated floors, fancy fixtures, soft towels, and a range of personal care products.

For many, the bathroom is a personal sanctuary – a place to de-stress with a hot bath or long shower.

Contrast this with bathrooms of the past, which were mostly about function. The focus was hygiene, not comfort or style.

Although privacy has always been linked to bathrooms, the emphasis on luxury and relaxation that we see now wasn’t there back then.

Understanding the journey from luxury to necessity gives us a clear picture of why old houses were designed with just one bathroom.

As our needs and views evolve, so does home design, reflecting our changing tastes and lifestyles.

The Multi-Bathroom Era: Why It’s Now the Norm

These days, having multiple bathrooms isn’t just about luxury—it’s often a must-have. There are a couple of reasons for this. For one, we’re all juggling busy schedules.

With everyone in the family on the go, extra bathrooms can ease those hectic morning or evening rushes. Also, we’re all about individual privacy now.

It just feels right to have a bathroom for each family member or guest. It’s about comfort and privacy, values we hold dear today.

En-Suite Bathrooms: The Cherry on Top

Let’s talk about en-suite bathrooms. These are bathrooms attached directly to bedrooms. They’ve played a big part in the trend for more bathrooms in our homes.

Having an en-suite bathroom is convenient and feels luxurious. They’re a big hit in homes with teenagers or multiple adults.

Plus, for the main bedroom, the en-suite bathroom doubles as a private haven for relaxation and self-care, beyond just being a bathroom.

The Real Estate Scoop: More Bathrooms, More Value

The rise in multiple bathrooms in homes has also shaken up the property market. Homes with more than one bathroom are real crowd-pleasers.

They often fetch higher prices than similar homes with just one bathroom. This is particularly true in city markets, where every square foot counts.

In real estate terms, bathrooms can seriously boost a property’s value and desirability. That’s why, even during renovations, adding an extra bathroom is often seen as a smart investment.

It can make a property more appealing on the market and might even give a solid return on investment.

To wrap it up, the trend for more bathrooms in homes is a reflection of our evolving lives, needs, and values. It shows how home design adapts to societal changes, tech advancements, and market shifts.

As we look to the future, it’s clear that our homes will continue to change to meet our evolving needs and expectations.

Practical Implications of Owning an Old House with One Bathroom

Living in a one-bathroom house comes with its own set of hurdles. For starters, coordinating everyone’s morning and evening routines can feel like solving a tricky puzzle, especially in larger households.

Then, there’s the privacy issue, which can be a big deal for families with older kids or multiple generations. Not to mention, hosting guests can get a little awkward with just one bathroom to share.

Increasing Your Bathroom Count: Some Ideas

If the single bathroom life isn’t for you, there are ways to up your bathroom count in an old home. One option? Transform unused spaces.

Think closets, large bedroom corners, or even basement areas. These could potentially become your new bathroom.

If you’re feeling ambitious, building an extension for a new bathroom could work, but it’s usually more expensive and time-consuming.

Another idea might be to split a big existing bathroom into two, but that really depends on your home’s layout.

Renovating or Remodeling: What to Think About First

Before you dive into the deep end with a renovation project, there’s a lot to consider. Let’s start with cost.

Adding a bathroom can be pricey when you factor in construction, new plumbing, and all those fancy fixtures.

Next up is feasibility. Not all spaces are cut out for a bathroom makeover. They need to have access to your home’s existing plumbing system.

So, getting advice from a pro, like an architect or contractor, is super important. You should also think about how the renovation will impact your home’s value.

While an extra bathroom can be a plus for home buyers, you don’t want to spend so much that it outweighs your home’s potential value increase.

Lastly, if you’re living in a heritage home, any changes need to keep the original style in mind. Sometimes, you might even need permissions to make big changes.

In a nutshell, yes, a one-bathroom house can be challenging. But with some careful planning, it’s possible to bring older homes up to speed with modern needs, all while keeping their unique character.
