Professional Tub-to-Shower Conversion Services in Crystal Lake, IL

A tub-to-shower conversion (also called tub conversion to shower, bathtub-to-shower conversion, or converting a tub to a shower) involves removing the existing alcove tub, adapting the drain and supply lines, and building a shower assembly with a sloped base, waterproofing, and finished wall surfaces. We typically demo with an oscillating multi-tool for clean cuts at drywall/backer transitions and use a laser level to verify plumb walls and the shower pan pitch. For waterproofing, we commonly install Schluter-KERDI membrane or liquid-applied RedGard, then set tile using a polymer-modified thinset like MAPEI or LATICRETE.

This service solves issues that standard tub use can create—especially in Crystal Lake homes where older bathrooms may have dated plumbing and marginal moisture protection. High tub walls increase slip-and-fall risk; the CDC reports that about 3 million older adults are treated in emergency departments each year for fall injuries, and bathrooms are a common setting. We also see hidden problems behind tubs: wet stud bays, deteriorated gypsum, and mold staining from failed caulk joints at the tub flange. A properly built shower system addresses these by creating a continuous waterproof layer, a correctly sloped drain plane, and sealed penetrations at the valve and shower arm.

Our tub-to-shower conversion process starts with a site evaluation of framing, venting, and drain location, then moves into controlled demolition and prep. Step 1: we protect floors and isolate dust with a HEPA air scrubber and containment, then remove the tub and inspect the alcove. Step 2: plumbing adjustments are made with PEX or copper as needed, and the drain is set to the shower base using code-compliant fittings; if a linear drain is selected, we verify subfloor depth and joist direction before placement. Step 3: we install a shower base (acrylic, solid surface, or mortar bed), apply waterproofing per manufacturer specs, then complete tile or wall panels, valve trim (e.g., Moen or Delta), and final silicone sealing.

Materials and standards matter more in a conversion than many homeowners expect because the old tub surround often wasn’t designed as a true wet-area system. We build to IRC/IPC principles for drainage and venting, and we follow TCNA Handbook methods (such as B421/B422 assemblies) for wet-area tile work. Typical substrates include cement backer board (USG Durock) or Schluter-KERDI-BOARD rather than moisture-sensitive drywall in the spray zone. For grout, we often recommend epoxy grout (e.g., LATICRETE SpectraLOCK) in high-splash areas, and we use ASTM C920-rated silicone at changes of plane to reduce cracking and moisture intrusion.

To complete the conversion with a clean, durable finish, we also focus on details that prevent callbacks: accurate valve depth, consistent slope to drain, and correct fastener placement through waterproofing only where permitted. We set tile with a notched trowel sized to the tile format, verify coverage, and use a grout float and sponge technique that avoids washout and pinholes. Where glass is part of the scope, we coordinate tempered safety glazing and properly anchored blocking for future stability. The result is a shower that functions like a purpose-built installation rather than a cosmetic swap.

What's Included

• Code-aware plumbing and drain relocation planning (trap/vent alignment, drain pitch, and valve depth) to reduce leak and clog risks
• Low-threshold base options that can reduce step-over height by 10+ inches compared with many standard tubs, depending on existing framing and drain elevation
• Installations aligned with TCNA wet-area methods and IRC/IPC practices; waterproofing applied per manufacturer requirements (e.g., Schluter-KERDI or RedGard)
• Moisture-control build method using surface-applied waterproofing, laser-level layout, and HEPA dust containment during demolition
• Manufacturer-backed product warranties on selected systems (varies by material) and documented waterproofing installation steps for project records

Local Service in Crystal Lake

Crystal Lake homes—from older properties near Downtown Crystal Lake to neighborhoods around Four Colonies and the Route 14 corridor—often have bathrooms built with older tub surrounds and aging plumbing that aren’t ideal for modern shower waterproofing. Our local approach accounts for seasonal humidity and temperature swings in McHenry County, which can stress caulk joints and amplify condensation if ventilation is weak. We also coordinate scope with City of Crystal Lake permitting practices when plumbing changes are involved, and we plan material lead times so your tub-to-shower conversion stays practical for the way Crystal Lake households use their bathrooms year-round.
