Bathroom Remodeling in Mountainside, NJ
Almost three in four Mountainside homes were built in the 1950s and 1960s. Their bathrooms are solid, often original, and laid out for another time. We rebuild them for the long haul: a shower you can step into at any age, with a written price and one point of contact.
Built in two decades, kept for generations.
The borough split from Westfield Township in 1895 and then waited sixty years for most of its houses. Census figures show the median Mountainside home was built in 1957, and fewer than one in twenty predates 1940.
Mountainside had 2,046 residents in 1950, 6,325 in 1960 and 7,520 in 1970 (U.S. Census). The styles follow that burst: ranches and split-levels first, colonials on the later streets, many on lots that back up to the Watchung Reservation.
Those homes were built well, with mortar-bed tile and copper plumbing, and a surprising number have never had the bathroom gutted. What has worn out is the layout: one hall bath for the whole upper level, and a primary bath with a small stall shower.
Many of our Mountainside calls come from owners who have lived in the house for decades or bought it from the family that built it. The brief is usually the same: make it comfortable and safe for the long haul, not flashy.
What we look for in a Mountainside house
- Ranch baths on a slab: drain moves mean cutting concrete, so we plan the shower around the existing drain where we can.
- Split-level upper baths over the garage: insulation under the floor before a heated mat goes in.
- The stall shower in the primary is almost always the first thing to enlarge.
- Original fans get replaced with one ducted to the outside, and outlets get GFCI protection.
- Wall blocking for grab bars and a bench goes in during framing, whether you use it now or later.

A bench shower we built in the county.
In a Union County home we built a primary bath around a walk-in shower with a built-in bench, a hand shower, a recessed niche and a brushed gold sliding glass door over a low threshold, beside a freestanding tub. It is the shower most Mountainside owners describe at the first visit: easy to step into, a place to sit, nothing to climb over.

- Primary baths enlarged from the original stall by taking the adjacent closet.
- Hall baths with a tub for visiting grandchildren and a fan that clears the room.

- Schluter waterproofing behind every tiled shower.
What a shower costs in Mountainside.
Most Mountainside calls are about the shower, so the shower rows lead. On a slab, keeping the drain where it is holds a conversion toward the lower part of its range. Every number comes from our NJ cost guide.
| Project | Labor only |
|---|---|
| Tub-to-shower conversionThe tub comes out and a tiled shower goes in, in the same spot. | $6,500 – $16,750 |
| Walk-in shower rebuild, same footprintThe old stall comes out; a bigger opening, a bench and glass go in. | $7,000 – $16,750 |
| Curbless shower, same footprintThe floor is recessed so there is no step. Depends on the slab or the joists. | $8,500 – $18,500 |
| Primary bath, new layoutThe stall grows into a closet, often with a moved drain. | $30,000 – $50,000+ |

Start with the calculatorPermits at Borough Hall.
Mountainside runs a permit through three reviews, zoning, a site review and then the subcodes, which the borough says can take up to twenty working days. We file early and plan the start date around it. Payments follow the phases; see the ways to pay.
Visit
Thirty minutes to measure, check the slab or the joists, and hear what you need from the room.
Scope and filing
A price by phase, in writing. When a permit is required, we file with the borough's construction office at 1385 Route 22 East.
Build and inspect
Plumbing and electrical inspections happen on Tuesday and Thursday afternoons, booked online a day ahead, so we schedule rough-in to meet them.
