Expert Walk-In Shower Installation in Des Moines, WA

Walk-in shower installation is one of the most practical upgrades a Bonney Lake homeowner can make. Many homes in the area were built with builder-grade tub-shower combos that are now dated and hard to maintain. Masis Contractor LLC replaces those setups with custom walk-in showers built for daily use. As an owner-operated family business, we handle every step ourselves: demolition, waterproofing, shower pan and drain work, tile, glass, and fixtures. We assess your floor framing and drainage before any work begins, so the finished shower fits your bathroom correctly. Bonney Lake's damp Pacific Northwest winters make proper waterproofing especially important. Moisture that gets behind walls causes rot and structural damage over time. We seal every layer before tile goes up. Whether you want a curbless entry, a built-in bench, or a tiled niche, we build it to your space. Call Masis Contractor LLC to get started on your Bonney Lake walk-in shower.

What's included
