One day bathroom remodel: what fits in a day, what doesn't

→Not sure where to start? Take the Bathroom Check.About 2 minutes. Rough answers are fine.

Before you sign up for a one day bathroom remodel, find out exactly what is being installed. If it is a liner or wall-panel system fitted over your existing tub or surround, it isn't a full remodel: nobody opens the wall to see what is behind it. That can be the right answer, but only when the bathroom underneath is sound.

What a one day bathroom remodel is

Treat "one day" as a sales label, and start by asking the seller exactly what they will install. Does the tub stay and get a liner, or does the tub opening become a shower base with wall panels around it? What are the panels made of? Which fittings (taps, shower head, door or rod, grab bars) are in the price?

Then ask what the job leaves out. If the plan is to fit a system over the existing surface, the quote should say so, and it should also say whether anyone will remove the old surround, look at the wall behind it, or move any plumbing. Over a sound surface that can be a fair trade. You're just buying something different from what most people mean by "remodel". If the timeline is what's pushing you toward it, how long a bathroom remodel takes shows what a conventional job's weeks are spent on.

What a day can cover, and what it can't

Ask which of these their one day covers: fitting a liner or panel system over a standard tub or surround, swapping fittings where they already are, adding grab bars, or converting the tub opening to a shower base on the same drain.

Ask harder questions about these:

• Moving plumbing or changing the layout. Ask whether putting a drain or valve in a new spot means opening walls or floors, and ask your local building department whether that needs a permit and an inspection; do you need a permit to remodel a bathroom explains the pattern. If a permit is needed, the contractor should pull it. The FTC lists asking you to get required building permits among the signs of a home improvement scam.
• Repairing water damage behind the wall. This is the one that matters most. A system fitted over the old surround hides whatever is behind it. The EPA's guide to mold and moisture says the key to mold control is moisture control, that mold can be hidden on the back side of drywall or paneling, and that if you clean up mold but don't fix the water problem, the mold will most likely come back. It also says not to paint or caulk over moldy surfaces. Panels fitted over a wet wall leave the water problem where it was.
• Waiting before the first shower. Ask the installer whether "one day" means the day of installation or the day you can shower again, and get that answer in writing.
• Lead-safe work in an older house. If your home was built before 1978 and the job disturbs painted surfaces, EPA's Renovation, Repair and Painting rule requires anyone paid to do it to be certified in lead-safe work practices. That covers every firm, sole proprietors included.

When it's the right answer, and the other routes

A one-day system makes sense when the bathroom is sound, nobody has seen signs of a leak, and getting a tub wall out of the way quickly matters more than rebuilding the room. That's often the situation when a parent can't safely step over a tub anymore. If that is what's driving this, the Eldercare Locator can connect you to help in your community.

It's the wrong answer when the bathroom is old and there's any sign of water: soft spots, stains, loose tile, a musty smell. Then the wall needs opening, and covering it means paying to make a problem harder to find.

Here are the routes, starting with the one that asks least of you:

What the liner route costs, and why there's no published price, is covered in what a one-day bath system really costs. The two ways to get a walk-in shower are compared in walk-in shower cost, and the conventional conversion in tub to shower conversion cost.

How the one day bathroom remodel sale works

If the system is offered at an in-home visit, the steps of that visit are laid out in what happens at an in-home bath sales visit. What matters here is the federal rule that applies once you sign at home.

The FTC's Cooling-Off Rule (16 CFR Part 429) covers a sale of $25 or more agreed at your home. The definitions say it applies even when the salesperson came because you invited them. Under the rule:

• You can cancel until midnight of the third business day after the sale, for any reason. Business days include Saturdays but not Sundays or federal holidays.
• At signing, the seller must give you a dated contract or receipt with its name and address and a statement of your right to cancel, plus two copies of a Notice of Cancellation form. It must also tell you about the right out loud.
• The contract can't include a waiver of your right to cancel.
• If you cancel, the seller has 10 business days to refund your payments and cancel any note you signed.
• The seller can't sell or assign your loan paperwork to a finance company before midnight of the fifth business day after signing.

The FTC's consumer guide to the rule suggests signing and dating one copy of the cancellation form, mailing it before midnight of the third business day, and using certified mail so you have proof. It also lists the main exceptions, which include repair or maintenance visits you asked for and sales needed to meet an emergency. Under the definitions, the emergency exception only applies if you started the contact and gave the seller a separate dated and signed statement, in your own handwriting, describing the emergency and waiving the right. A one day bathroom remodel sold at a scheduled visit is rarely an emergency. The step-by-step version is in how to cancel a bathroom contract.

Bottom line

A one day bathroom remodel puts a new surface over a sound bathroom, and sometimes that's exactly what a household needs. A system fitted over the old surround leaves the wall behind it as it is, so ask in writing whether it moves any plumbing and what happens if they find water. If it's sold at your table, don't let the visit set the pace: get both routes priced first. And if you signed in a hurry, you still have three business days.

Common questions

Is a one day bathroom remodel a real remodel?

Ask the seller exactly what will be installed. If the offer is a liner or wall-panel system fitted over the existing tub or surround, it is not a remodel in the usual sense: the wall behind it isn't opened, so whatever is there stays as it is.

Can a one-day job fix water damage or mold behind the wall?

No. A system fitted over the old surround covers what is behind it. EPA's guidance is that if you clean up mold but don't fix the water problem, the mold will most likely come back, and that moldy surfaces should not be painted or caulked over.

Does the three-day cancellation rule apply if I invited the salesperson?

Generally yes. The Cooling-Off Rule's definition of a door-to-door sale (16 CFR 429.0(a)) covers sales of $25 or more made at your home, including those in response to or following your invitation. You can cancel until midnight of the third business day after the sale, and Saturdays count as business days.

Who should pull the permit if one is needed?

The contractor. The FTC lists asking you to get the required building permits as a sign of a home improvement scam. Ask your local building department whether the job needs one.

My house is old. Does that change anything?

If it was built before 1978 and the job disturbs painted surfaces, EPA requires anyone paid to do the work to be certified in lead-safe work practices. Ask to see the firm's certification.
