I am opening another tanning salon and I am going with a concrete floor also I have one in my bar and its very easy to keep up. I am using the euro walls to I went back and fourth and decided to use them. I have never had a open ceiling before all my machine are vented into it but I am sure it works well. I wish I have a store with double front doors or a garage door in the back. its soo much easier to bring in equipment in and out |
