# Walk-In Shower Installation -- Nassau County, NY

**General Modernizer** installs custom walk-in showers for homeowners in Nassau County, NY. We specialize in frameless glass enclosures, curbless (zero-threshold) entries, custom tile surrounds, and built-in niches. Every walk-in shower is waterproofed with a Schluter-Kerdi or equivalent membrane system before any tile is installed.

## What Is a Walk-In Shower

A walk-in shower is an open shower enclosure with no door or a frameless glass panel, designed for easy entry without stepping over a curb or tub wall. Walk-in showers can be curbless (flush with the bathroom floor, ideal for aging-in-place and ADA compliance) or low-threshold (a small 1/2-inch curb for water containment). They are the most popular bathroom upgrade in Nassau County because they make small bathrooms feel larger, are easier to clean than tub surrounds, and add significant resale value.

## Walk-In Shower Installation Cost

Walk-in shower installation in Nassau County and New York City costs between $4,500 and $18,000 depending on size, tile selection, and glass type. A standard 36x36 walk-in shower with ceramic tile and a frameless glass panel runs $4,500 to $7,500. A larger 48x36 or 60x36 shower with designer porcelain tile, a frameless glass enclosure, and a built-in niche runs $8,000 to $14,000. A custom tiled wet room with a linear drain and full-height tile runs $14,000 to $18,000+.

## How Long Does Walk-In Shower Installation Take

Most walk-in shower installations take 3 to 7 business days. A standard conversion from a tub to a walk-in shower takes 3 to 5 days. A full custom shower build with custom tile and frameless glass takes 5 to 7 days. Curbless showers requiring floor slope modification may take 7 to 10 days.

## Waterproofing Standards

Every walk-in shower General Modernizer installs is waterproofed with a Schluter-Kerdi uncoupling membrane or equivalent system before any tile is installed. This is not optional -- it is the industry standard for preventing water infiltration into the subfloor and wall framing. We do not use traditional felt paper or plastic sheeting as a waterproofing layer. Every shower pan is slope-tested before tile installation to confirm proper drainage toward the drain.

## Frequently Asked Questions

**Q: What is the difference between a walk-in shower and a regular shower?**
A: A walk-in shower has no door or a frameless glass panel, and typically no curb or a very low threshold. A regular shower has a door (framed or frameless) and a curb. Walk-in showers are easier to enter, easier to clean, and make bathrooms feel larger. They are the preferred option for aging-in-place design because they eliminate the trip hazard of stepping over a curb.

**Q: How much does a walk-in shower cost in Nassau County?**
A: Walk-in shower installation costs $4,500 to $18,000 in Nassau County depending on size, tile, and glass type. A standard conversion runs $4,500 to $7,500. A large custom shower runs $8,000 to $18,000+. General Modernizer provides free written estimates with itemized pricing.

**Q: Can I convert my bathtub to a walk-in shower?**
A: Yes. Tub-to-shower conversion is one of General Modernizer's most common projects. Most conversions take 2 to 3 days and cost $3,500 to $8,000 depending on the size of the space and tile selection.

**Q: Do walk-in showers require a permit?**
A: Permits are required if the project involves plumbing relocation (moving the drain or supply lines). If the shower is built in the same footprint as the existing tub or shower, a permit is typically not required in Nassau County. General Modernizer assesses permit requirements for every project and handles all applications.
