Mike and Casey were on time, professional and did an excellent job. My project was completed in one day. I can hardly wait to use my new shower. I highly recommend Mike and Casey as installers. They are awesome and professional.

I absolutely love our new bath and shower! The whole process working with Lifetime was great! Hallie was very communicative during the ordering process and was great to work with. Mike and Casey were our installers and they were awesome! Very professional, kind and personable. It’s a dirty job and they were very clean and courteous about our home getting dusty and dirty. Overall I’m satisfied so far with how things turned out!
