Basement bathroom addition

Lead remodeler · Private residence — Arvada, CO · Aug – Sep 2025 · 4 weeks

Added a full three-quarter bath to an unfinished basement: new rough-in through the slab, an up-flush system for the shower, and a layout that kept the egress window clear.

Inspections passed first time

Turned a storage corner into a legal, permitted full bath, which let the owners rent the basement as a separate suite the following month.

Reviews

Cutting into the slab sounded terrifying and Marcus walked us through every step. He pulled the permits himself and we passed every inspection without a callback.
