Adding a bathroom to a DMV home means routing new plumbing to an existing stack or adding a new stack — and that routing determines cost as much as the fixtures do. Dzala evaluates the plumbing route during the estimate visit so the quote reflects the real scope, not the best-case scenario.
Why Dzala
Bathroom additions with honest estimates
The first question in a bathroom addition is always the plumbing route. We map it at the estimate visit — how far to the stack, what is in the way, whether a new stack is needed. You get a quote that reflects the real route, not the optimistic one.
