"John from Clearwater Spa Company was very responsive to our home improvement job inquiry. After he found out that our Jacuzzi hot tub would be too old to replace the parts and be worth the money, he advised us to simply replace the Jacuzzi tub with a non-jacuzzi one and hire a local plumber to get it done. We greatly appreciate his detailed suggestions and very helpful consultation. Additionally, he explained to us all of the detailed diagnosis in great patience and truly put the customer first."

Born from a simple idea: the world's healthiest cultures don't just chase wellness — they live it together.\n\nCape Sauna Club is not an attempt to copy Norway, Japan, or Germany and drop it onto Cape Cod. That would miss the point entirely. This is about taking the essence of what makes those traditions so meaningful and shaping it into something that feels right here, on the Cape.\n\n"I'm not going to pretend we built something identical to what I found in those places. We didn't. We're on Cape Cod. We're in a barrel sauna, not a century-old Nordic longhouse. But the thing underneath it — the reset, the silence, the connection — that's exactly what we're bringing here."

"My original contract with O Donnell Pools was 2 years ago to have them remove all tiles, resurface and paint my gunite pool and install all new tiling. When they completed the work the 25 year old pool looked brand new. I then contracted with them for opening, closing and weekly service and have been extremely pleased with the services provided."

Pool and Spa Servicing FAQs, answered by experts

Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including Pseudomonas aeruginosa, bacteria that can cause hot tub rash, or Legionella bacteria, which can cause respiratory illness.

The cost to repair a hot tub or spa ranges from about $170 to $550, depending on the repairs needed. Some of the most common hot tub repairs include leaks, clogged filters, and tripped GFCI breakers. If it’s an electrical problem, you should contact a professional hot tub repair service. Don’t DIY electrical repairs on a hot tub, as poorly repaired wiring can make the hot tub a serious electrocution hazard.

How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months. If you use your swim spa throughout the seasons, it’s a good idea to set up a quarterly deep cleaning schedule. The ideal instructions should be in the owner’s manual.

You can drain a hot tub very quickly by using a submersible pump rather than the hose-sized drain at the bottom exterior of the tub. A pump can move up to 30 gallons per minute, draining your hot tub in no time. Using the regular drain can take up to two hours.

Yes, air baths are good for you. They promote relaxation, improve circulation, and can even hydrate your skin. Since they’re gentler than water jets and whirlpools, they are a good choice for a wide range of homes and users, from children to adults. You can maximize the benefits by using them regularly for stress relief and by pairing the bubble effects with calming music, low lighting or chronotherapy, aromatherapy, and other relaxation techniques.
