"The people on the phone and the workers that worked at my house were fantastic. Damien and Ernest were the installer's top rate people. Jack, their license plumber was polite and funny. The only person we didn't care for was Keith He only stopped by to look at what was going on. He was a little rude to my wife and Made her feel Like she was second class in her own home. We Were very shocked by that. We would definitely recommend Jacuzzi to our friends."

"Great presentation by Nick. Very nice, informative, professional and knowledgeable. Super quality products and vert6competitive pricing. Because of very busy installation schedules, it will take 4-6 weeks before walkin shower remodel can happen. We can wait, no problem. It will be worth it."

"When the service guy arrived he asked what our problem was and showed up the price chart. He was not pushing any other service and gave us all the details on why the drain was clogging. He wore lilttle booties to protect our floor and put a rug down while he worked. Used the rotor to unclog the sink and he even double checked that the drain was cleared. Also came with a warranty if the same drain should clog again.

"Great sales and honest woman owned! Loved the outcome and they were very understanding when I had to push the project out due to the death in the family and my responsibility for expenses. Tammy is wonderful and her crew knows what they are doing. I have contracted her to upgrade the second bathroom also. Love the results of the master and cannot wait to see the 2nd bath remodel!"
