Wish I could have tried before purchase
I love baths, especially those with air jets. We had to replace our tub and choose the Sia based on features and positive reviews. The good aspects are the low profile and size fits my husband and I. However the negatives outweigh and I wish I hadn’t purchased. When turning on the jets the ones in the lumbar area spray all over behind your back and head. End up with a mess around the tub! And there is no way to turn them off and just enjoy the jets from the bottom (floor) of the tub. That should be an option. So I end up with a jetted tub that I rarely use because of the mess and discomfort of water spraying all around my head and out of the tub. Used to take baths several times a week, use this less than once a month. Also hate the only available overflow drain control. It feels flimsy, plastic and is too large for the sleek tub.

Hello DR-DR. Thank you for taking the time to review your experience with this tub. While there is no way to turn off the lumbar air jets, you are able to decrease the speed/intensity of the air jets. Press the blower operation button to turn on the air jets. Use the decrease toggle button to decrease the speed/intensity. If you have the wave feature on as well, you can also use the decrease toggle button to lower the intensity. Another issue may be the level at which you are filling the tub. If the tub is filled up too high, it may cause splashing. It is recommended that you fill the tub halfway, get in the tub, then continue filling it until it is about 1-2” from the overflow. We do offer another drain kit that may be more suitable for your design needs. Please copy and paste the URL below into your web browser for color and purchasing options. We appreciate your suggestion regarding being able to turn off just the lumbar jets. Your comments and feedback help us to improve our products and services to ensure our consumers receive the best experience. If you continue to experience issues with the air jets, please give us a call at 1.800.288.4002, Mon. to Fri., 6 AM to 5 PM, PST, and reference case number 00796125. We stand ready to support you and our products in hopes of creating a more relaxing bath experience. Alyssa- Jacuzzi® Official https://www.build.com/jacuzzi-pg35/s1286924?uid=3058165
    It’s fine. Expensive but we love baths
    We installed the first of 2 of these tubs about a month ago. The big issue is how much water you have to have to stop the lumbar jets from spraying into my hair and all over the wall. I feel like I have to be in the ready position and maneuver to get the jets turned on so we don’t have a huge mess. I don’t water the water so deep but I have no choice. I’m looking for a way to suppress those top jets and can’t find one. Also, I’m having a heck of a time finding a realistic detailed owners manual. Something that goes into detail with how to operate all the features. We also had the bottom air come on while the tub was not in use. We were in the living room and heard something from the bathroom and the air was blowing on the floor of the tub. We just unplugged it.
      Love this tub so much we bought it twice!
      We installed this tub in our first house and never regretted it. When we moved I mourned my Sia tub. After two years my husband and I decided we needed to have our tub back. I looked at other companies and models even tried out a few but nothing compaired to the Sia. Unfortunately we do not have the space for the bigger 72 inch model we had before we had to go with the smaller size. I was a little hesitant but honestly there is plenty of room for both of us, even with him being 6’5” and me at 5’10. In fact I enjoy the foot jets much more in our smaller model. Also, I’ve never noticed jets spraying everywhere and making a mess. I am thinking the reviewer who complained about there jets spraying my need to adjust the jets, the jets are fully adjustable and can be positioned in different directions as well as turned off. We are planning on building onto our house in the near future to add a bigger master bedroom and when we do without a doubt we will be adding a Sia to the new bathroom.
