Shower Builds and Upgrades In Chicago
Spa feel. Solid waterproofing. Built to last.
Built for daily comfort and durability
At Costello Carpentry, we do Shower Builds and Upgrades that look great and survive daily use. From sleek walk-ins to frameless glass enclosures, we prep the substrate, waterproof correctly, and set tile with tight, consistent lines.
We form and level pans, set proper slope to the drain, and use modern membranes so water goes where it should. Niches, benches, and shelves are integrated cleanly, and every penetration is sealed.
The result is a shower that feels bigger, drains properly, and is easy to keep clean — without surprises months later.

Frequently Asked Questions
How long does a typical shower build take?
Most projects take 3 to 5 days based on size, layout changes, and cure times. Complex glass or custom stone can add a day for templating and install.
Do you waterproof and flood test the shower?
Yes. We install membranes and backer boards to spec, seal every penetration, set proper slope, and perform a 24-hour flood test where applicable.
Can you build a curbless or low-threshold shower?
Yes. We recess or reframe the subfloor, set the pan to height, and coordinate drains and glass so entries are smooth while maintaining correct pitch.
Will you work with tile and fixtures I already purchased?
Yes. Share sizes, quantities, trim profiles, and fixture specs so we can confirm coverage, clearances, and finishing details before we start.
Do you relocate plumbing or keep it in place?
Both options are available. We can swap valves in place or move supplies and the drain to match a new layout, then pressure test all connections.
What glass options do you offer?
Frameless or framed doors and panels. We template after tile for exact fit, set hardware for smooth close, and seal as required for a tight finish.
How do you control dust and protect adjacent spaces?
We isolate the work zone with plastic, run targeted extraction, use wet cutting when possible, protect paths, and clean the area at the end of each day.
What warranty do you provide?
Workmanship is covered for one year. Manufacturer warranties for membranes, tile, grout, and glass hardware remain in place with documented install details.
