"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

When your hot tub is completely dry, there is typically no need to introduce antifreeze into the plumbing. However, if you desire an extra layer of protection against potential freeze damage, you can consider adding some RV antifreeze to your hot tub lines. Just ensure that you use RV antifreeze specifically, as automotive antifreeze is highly toxic and should be avoided.

Hot tub heaters typically last seven to 10 years, though some might only last five years if not properly maintained. You can maximize your hot tub heater’s lifespan by ensuring the water’s pH level is properly balanced.

In most cases, it is safe to clean a hot tub with vinegar. You will want to verify that your hot tub manufacturer lists vinegar as a safe cleaning product; however, given that vinegar is chemical-free, cleans, deodorizes, and is safe for people and pets, it is usually a good option. You can use vinegar to clean the hot tub shell, interior and exterior spa surfaces, hot tub jets, hot tub filter, and other parts. It is considered a strong, safe, and natural cleanser that can kill bacteria, remove mold and mildew spores, erase water spots, and remove hard water stains.

If water is left inside the hot tub pump over a cold winter, it could freeze and severely damage the pump, water lines, and jets. That can cause leaks, which require very expensive repairs. Freezing or leftover water can stain and damage the hot tub shell, which leads to replacement. Even in mild climates, leaving sitting water in the tub or pipes for a long period of unuse is a bad idea, since disinfecting chemicals fade and the water can develop bacteria, algae, and other big headaches when it’s time to use the tub again.

Many people find saltwater tubs worth the upfront expense. They cost less to maintain than traditional hot tubs, so you can save in the long term. Maintenance is also easier, typically involving balancing the pH and cleaning the tub rather than adding chemicals. They’re also gentler on sensitive skin, and you won’t walk away with a strong chlorine odor.
