Tub-to-Shower Conversions: What Seacoast Homeowners Should Know

A tub you step over but rarely fill is one of the most common things we are asked to change, and for good reason. Converting it to a walk-in shower can make a bathroom feel larger, easier to use, and ready to keep serving you for decades. It is a popular project on the Seacoast, and a smart one when you go in knowing the few things that matter.

When a conversion makes sense

The honest test is simple: do you actually take baths? If the tub mostly collects dust and forces you to climb over a wall every morning, a walk-in shower will improve your daily life immediately. Showers are easier to step into, easier to clean, and they open up the visual space a bulky tub was eating.

This is especially true in a smaller bathroom, where a tub takes up a footprint a well-designed shower can use far better. There is more on making tight spaces work in our guide to small bathroom remodel ideas.

The one thing to check first: resale

Here is the caution we give every homeowner. Removing a tub is fine, removing your home’s only tub is the thing to think twice about. Many buyers, especially families with young children, expect at least one bathtub in the house. If you have a tub in another bathroom, converting this one is an easy call. If this is your only tub, weigh it carefully or plan to keep a tub elsewhere.

Plain conversion or fully tiled walk-in

There are really two versions of this project, at different price points:

  • A straightforward conversion keeps the plumbing roughly where it is and swaps the tub for a shower base and surround. It is the friendlier number and a real improvement.
  • A fully tiled, curbless walk-in shower is the one people fall in love with. It is custom tile, a frameless glass panel, and a floor reworked to drain without a lip to step over.

The fully tiled version costs more, mostly because a curbless floor has to be built to slope and drain correctly, which is real carpentry and waterproofing under the surface. We price the finished shower as one fixed number so the waterproofing and prep are in it, not left out to make a headline look cheaper.

Why curbless is worth a serious look

A curbless shower, with no threshold to step over, is the single best thing you can do to keep a bathroom working for you as the years pass. It reads clean and modern today, and years from now it still works with a shower chair or a walker if it ever needs to, with no second renovation.

That future-proofing is quiet and invisible, which is the whole point. It is the same thinking behind aging-in-place design: make the choice once, while the wall is already open, and never have to think about it again. The one detail we push hardest on any shower build is adding solid blocking in the walls for grab bars you may want someday, because it costs very little now and a great deal later.

A bathroom that fits you longer

A tub-to-shower conversion is one of those projects that pays you back every single morning and keeps paying for decades. Done well, it makes the room feel bigger now and keeps it usable far into the future.

If you have a tub you never use and a bathroom that could work harder for you, we would be glad to take a look. Get a custom estimate in about two minutes below, or tell us about your project.

Common Questions

Frequently Asked

Is it a good idea to convert a tub to a shower?
For many homeowners, yes. If you rarely take baths, a walk-in shower is easier to use, easier to clean, and makes a bathroom feel larger. The one caution is resale, because if it would leave your home with no tub at all, that can matter to future buyers with young children, so it is worth keeping a tub somewhere in the house.
How much does a tub-to-shower conversion cost?
It varies with the shower you choose. A straightforward conversion that keeps the plumbing in place costs less, while a fully tiled, curbless walk-in shower with custom glass costs more because it involves reworking the floor to drain correctly. We price the finished shower as one fixed number so you know exactly what you are getting.
What is a curbless shower and is it worth it?
A curbless, or zero-threshold, shower has no lip to step over, the floor flows straight in. It looks clean and modern, it is easier to clean, and it is the single best thing you can do to keep a bathroom usable for decades. It costs a bit more because the floor has to be reworked to drain properly, and for most homeowners planning to stay in their home it is worth it.
Will removing my only tub hurt resale value?
It can, if it leaves the home with no bathtub at all. Many buyers, especially families with small children, want at least one tub. The simple rule is to convert a tub you do not use to a great shower, as long as another tub remains somewhere in the house.
