Frequently Asked Questions

We get this question all the time, but it’s really like asking how long a piece of string is. How big is the bathroom? Does it have a shower? Is it a standard shower or is it a double-sized shower with multiple rain shower heads? Does it have a bath hob? How many wet areas are required over the entire job? Questions like that can seriously affect pricing. We’re talking a difference of hundreds or thousands of dollars based entirely around your room and job specifications.
