What actually happens during conversion
The contractor removes the existing tub, inspects the framing and plumbing, repairs damaged substrate, installs or builds the shower base, waterproofs the walls, installs tile or shower panels, updates the valve and trim, installs glass or a curtain system, seals the work, and cleans the space. The exact process depends on whether the homeowner chooses an insert, tile, or custom walk-in shower.
Aging-in-place and accessibility upgrades
Many Johnson County homeowners convert tubs to showers because stepping over a tub becomes unsafe. Lower thresholds, grab bar blocking, handheld shower heads, benches, wider openings, non-slip tile, and better lighting can make the bathroom safer without making it look institutional.
