Guest Bathroom Remodeling Project in Langhorne, PA

At 35 square feet, this Langhorne guest bathroom is compact — but the scope of the remodel was anything but. Full demolition, electric heated flooring, floor-to-ceiling polished marble-look tile, a matte black faucet and shower panel system, a bidet toilet, and a recessed niche in the tub wall. This was a guest bathroom that the homeowner wanted to feel finished and deliberate, not like a second-priority room.

Belmax Remodeling completed this project in February 2026 at a contract value of $15,000.

Demolition and Substrate Preparation

The project started with full demolition of the existing bathroom. In a 35-square-foot space, there is no room to build over old materials — everything has to be right from the substrate up, or the tile work will show it eventually. Moisture-resistant green board was installed on the walls, and self-leveling underlayment was applied to the floor before any tile work began. Leveling the floor properly is a step that determines whether the final tile installation looks flat and consistent or slightly off — visible to anyone who spends time in the room.

Heated Floors and the Tile Selection

An electric heated floor system was installed beneath the tile — a feature that is increasingly common in bathroom remodels but still distinctive enough to change how the room feels in cooler months. The system runs under the black marble hex mosaic floor tile, which was chosen in part for its visual contrast with the lighter wall tile and in part for its practical benefit: the grout lines in a mosaic pattern provide better traction underfoot than large-format tiles on a bathroom floor.

The wall tile is polished marble-look porcelain, installed floor to ceiling on the tub surround and carried across the remaining bathroom walls as well. Running tile all the way to the ceiling is a decision that changes the visual scale of a small room. In 35 square feet, stopping tile at a standard height can make the space feel shorter and more segmented. Taking it to the ceiling keeps the eye moving upward and makes the room feel larger than it is.

The Tub Area and Shower System

A new bathtub was installed as the centerpiece of the tub enclosure, tiled on all sides with the polished marble-look porcelain. A recessed niche was built into the tub wall for storage — positioned within the tile layout so it does not interrupt the continuous tile surface. Getting the niche placement right during the framing and tile-setting stage is what allows it to look intentional rather than like an afterthought.

The shower panel system is matte black with multiple water delivery options and body jets. It pairs with the matte black widespread faucet on the vanity to create a consistent finish across the fixtures — a detail that holds the design together in a small space where every surface is visible at once. A polished engineered marble threshold at the shower curb completes the transition between the tub area and the rest of the floor.

Vanity, Lighting, and Electrical

The homeowner supplied the single-sink vanity, which was installed and connected with a new matte black faucet. A medicine cabinet with mirror was mounted above it, with a vanity light fixture overhead sized to provide even illumination across the sink area. Lighting in a small bathroom matters more than it does in a larger space — poor vanity lighting affects both the practical use of the mirror and the overall feel of the room.

A dedicated electrical outlet was installed for the bidet toilet — a code requirement when adding that kind of fixture that is easy to overlook during planning but has to be roughed in before the tile work closes up the walls. The homeowner’s exhaust fan was also installed as part of the electrical phase.

What Changed

This guest bathroom now operates at a noticeably different level than the original space. The heated floor, the full-height tile, and the matte black fixture package give the room a finish quality that a guest bathroom at this price point rarely has. More importantly, all of it is backed by proper substrate preparation, correctly placed rough-in work, and a tile installation that was done in the right order — which is what determines whether a bathroom looks this way in ten years or starts showing problems in two.

Bathroom Remodeling in Langhorne

Langhorne is a Bucks County community where many homes have bathrooms that have not been updated in decades. Guest bathrooms in particular tend to get deprioritized — they function, but the finishes are dated and the layout has not kept up with how the rest of the house has been maintained. When homeowners in Langhorne decide to update a guest bath, the question is usually how far to take it. This project is an example of what a full remodel at $15,000 looks like in 30 square feet — everything replaced, with some features (heated floor, full-height tile, body jet panel) that go beyond a standard update.
