Only One Bathroom in the House? Here's How to Get Through the Remodel

Only One Bathroom in the House? Here's How to Get Through the Remodel

September 7, 2026

It's the question we hear more than almost any other, and it usually comes with a nervous laugh: "We only have one bathroom. How does this even work?"

It's a fair concern. A huge share of Metro Detroit's housing stock — the postwar bungalows in Royal Oak and Ferndale, the 1950s ranches in Warren and Livonia, the older homes in Dearborn and Grosse Pointe — was built with exactly one full bathroom upstairs and maybe a half bath in the basement if you were lucky. Remodeling that one bathroom isn't impossible. But it does require a different kind of planning than a house with two or three.

The honest answer: you won't be without a toilet the whole time

The biggest misconception is that the bathroom is unusable from demolition day to final walkthrough. That's not how a well-run job works. On most single-bathroom projects, the goal is to minimize the number of days the toilet is genuinely out of commission — and that's usually a much shorter window than the overall project length.

Here's roughly how a typical bathroom remodel sequences out. Demolition takes a day, sometimes two if there's tile over mortar bed or an old cast iron tub coming out. Then comes rough plumbing and electrical, framing changes, and inspections if the scope requires permits. Waterproofing and tile setting are the longest stretch, because thinset and grout need cure time you can't rush. Then fixtures, glass, paint, and trim at the end.

During most of that middle stretch, the toilet is either reinstalled temporarily or the space is simply off-limits during working hours but the room isn't a construction zone overnight. Water to the whole house is typically only shut off for short, scheduled periods — a few hours here and there while supply lines are cut in — not for days on end. Ask about this specifically when you're planning, because it's the detail that affects your daily life most.

Realistic backup options

For the days the bathroom truly is unavailable, homeowners in single-bathroom houses generally land on one of a few approaches:

A basement toilet. If your house has an old basement stool — even a marginal one — this is your best friend. It's worth having it checked and serviced before the project starts rather than discovering the shutoff valve is seized on day one.

Family, neighbors, or a gym membership. Not glamorous, but it works. A month-to-month gym membership for showers is a common and inexpensive solution, especially for households where everyone leaves for work or school anyway.

A short stay elsewhere. Some homeowners plan a few nights away timed to the tightest part of the schedule. If you have relatives nearby, coordinating that in advance beats scrambling.

A portable rental. Less common for residential jobs, but it exists, and for a household with small kids or mobility limitations it can be worth the cost.

Timing matters more than you'd think in Michigan

If you have any flexibility on scheduling, think about the season. Summer is easier for single-bathroom households — kids are out of school, schedules are looser, and if someone needs to shower at a relative's house it's not a February drive on unplowed side streets. On the other hand, contractors book heavily in spring and summer. Winter and early spring projects often move through with fewer competing jobs.

We're typically booked out two to three months, though reschedules sometimes open up sooner slots. That lead time is actually an advantage for a one-bathroom house: it gives you weeks to line up your backup plan, service the basement toilet, order fixtures so nothing holds up the finish work, and talk to whoever's letting you use their shower.

What slows a single-bathroom job down

Two things extend timelines more than anything else: surprises behind the walls and materials that aren't on site. Older Metro Detroit homes hide rotted subfloor around toilet flanges, galvanized supply lines that crumble when disturbed, and wax-ring leaks that have been quietly soaking joists for years. None of that is avoidable, but a good contractor budgets time for it instead of pretending it won't happen.

The materials issue is entirely preventable. Have every fixture, tile, vanity, and piece of glass selected and ordered before demolition. In a house with two bathrooms, waiting a week on a backordered shower base is annoying. In a house with one, it's a real problem.
