Bathrooms in Portsmouth homes
Portsmouth ranges from downtown's antique homes and their plaster walls to newer condos in Pease and the west end. Both need a different approach to anchoring, and both are routine for us.
Older bathrooms in Portsmouth often mean cast-iron tubs, tile set in mortar, and plaster walls. A conversion is very doable, but it is planned around what is behind the wall, not just what is in front of it.
Condo bathroom work stays within the unit and follows association rules. Tub-to-shower conversions and grab bars are the most common projects we plan for condo owners.
Newer bathrooms usually have fiberglass or acrylic surrounds and standard framing, which makes conversions and grab bar installation straightforward.
Portsmouth is on the Seacoast at the mouth of the Piscataqua. Every visit starts from our base in Hampton, NH, and we come to you.

What is a tub-to-shower conversion?
The bathtub comes out and a low-threshold shower goes in its place, usually within the same footprint. You stop stepping over a tub wall several times a week, and the new shower is planned with grab bars, a seat if you want one, a handheld shower, and non-slip flooring from the start.
Can you add a bathroom on the first floor of my Portsmouth home?
Often, yes. A first-floor walk-in shower addition is one of our example projects. It starts with an assessment to find the right location relative to existing plumbing, then a plan and a budget before any work is scheduled.
How much does an accessible bathroom cost in Portsmouth?
It depends entirely on scope. Grab bars are the least expensive change and are installed the same day as a free in-home estimate. A comfort-height toilet is a small project. A tub-to-shower conversion or a new first-floor bath is a planned project with a written budget. We quote before work starts so you can decide with the numbers in front of you.
How long will the bathroom be out of service?
Grab bars and a comfort-height toilet are typically done in a single visit. A conversion or a new bathroom is scheduled as a project, and we plan the schedule with you so you know exactly when the room will be unavailable.
What is a comfort-height toilet?
A toilet with a taller bowl, roughly the height of a standard chair, which makes sitting down and standing up easier on the knees and hips. Paired with a properly anchored grab bar, it is one of the most effective small changes in the house.
Do you install grab bars in Portsmouth the same day?
Yes. Grab bars are installed during the same visit as your free estimate, with Moen® Home Care bars and hardware stocked in the vehicle. If the rest of the bathroom project comes later, the bars go in now. See grab bar installation in Portsmouth for details.
