Rated 4.8 out of 5 by 41 reviewers.





























Rated 4 out of 5 by Aventine spa service issues with mine were ultimately repaired by dealer - good spa - there is a very limited selection of small triangle shaped units on the market and we felt this was best choice May 26, 2011
























































Rated 4 out of 5 by Good for B & B Aventiene: One problem we have had is the finish is blistering (bubbles). We have two of these spas for our B & B May 26, 2011
























































Rated 3 out of 5 by jet wish offer more jet in rear where feet area and price is pretty expesive but overall good spa and easy to keep up with it . June 2, 2011
