Walk-In Shower Installation

Showers Designed for Easy, Safe Entry

Walk-In Shower Installation in Somerville for eliminating high tub thresholds and modernizing outdated bathrooms

Standard bathtubs create a 14 to 18 inch step-over barrier that becomes increasingly difficult to navigate as balance declines or joint stiffness limits leg lift. Inside & Out Home Improvement installs walk-in showers in Somerville that replace this obstacle with low-threshold or zero-threshold entries, allowing you to step or roll directly into the shower without lifting your foot significantly. The transition from tub to shower opens floor space and reduces fall risk during daily bathing.


The installation process involves removing the existing tub and surround, addressing any subfloor rot or water damage commonly found beneath old tub installations, building a custom shower pan with proper slope toward a drain positioned for efficient water flow, and applying waterproofing membranes before tile work begins. Drainage solutions must account for water volume and prevent pooling at the entry point, which requires precise pan construction and drain placement.


Arrange an on-site consultation to evaluate your current bathroom layout and discuss shower configurations that fit your space and accessibility needs.

How Walk-In Showers Address Entry Barriers

Walk-in shower construction centers on creating a watertight enclosure with minimal entry obstruction. Waterproofing systems extend beyond the shower footprint to protect surrounding walls and subfloor from moisture intrusion, using membranes that tie into the drain assembly and create a continuous barrier beneath tile surfaces. Proper slope must be built into the pan itself, typically one-quarter inch per foot toward the drain, so water doesn't rely solely on surface grout lines for drainage.


Once installation is complete, you'll step into a shower without hoisting your leg over a tub wall, reducing strain on hips and knees while lowering the risk of catching your foot on a high threshold. Frameless glass enclosures provide clear sightlines and easier cleaning compared to framed doors with metal tracks that collect soap residue and mildew. Floor surfaces use slip-resistant tile with enough texture to provide traction when wet but not so much that cleaning becomes difficult.


Shower dimensions vary based on available space, but most installations range from 36 by 36 inches to 48 by 60 inches or larger. Custom tile work allows pattern variation and niche placement for storage, while glass thickness and hardware style affect both appearance and long-term durability. Projects sometimes include bench seating, handheld shower wands, and multiple showerheads depending on your preferences.

Common Questions About This Service

Property owners usually ask about waterproofing methods, design options, and how shower installation affects existing bathroom layouts.


  • What prevents water from escaping a walk-in shower? Proper floor slope directs water toward the drain faster than it can reach the entry, while a slightly raised curb or strategically angled glass panel contains splash, though truly curbless designs rely entirely on slope and sometimes a linear drain positioned near the entry.
  • How is the shower pan made waterproof? Waterproofing involves applying liquid or sheet membranes over the mortar bed or foam pan base, wrapping up walls at least six inches, and integrating with a clamping drain assembly that sandwiches the membrane to prevent leaks at the drain connection.
  • Why do frameless glass doors cost more than framed? Frameless enclosures use thicker tempered glass, typically three-eighths to half-inch, which requires less structural support but costs more per square foot, and the hardware must be more robust since the glass itself provides rigidity without a surrounding metal frame.
  • What tile works best for shower floors? Smaller mosaic tiles create more grout lines that improve traction, and textured or matte finishes provide better slip resistance than polished stone, though Tennessee's hard water can cause mineral buildup on highly textured surfaces that require more frequent cleaning.
  • Can a walk-in shower fit where a standard tub was? Most standard tubs occupy 60 inches of wall length, which provides enough space for a comfortable walk-in shower, though the layout may shift to optimize door swing and fixture placement based on plumbing locations and available floor space.
