Disclaimer

The calculators and finders on PoolCareCalcs give planning estimates. They are not safety, electrical, structural or professional pool-service advice.

Estimates for planning

Every result on this site is an estimate based on the numbers you enter and on simplified formulas and default values. Real outcomes depend on your own situation, and defaults are examples, not quotes or promises. Please confirm anything important with the right professional, product label or official source before you act on it. Use of this site is at your own risk.

Chemical safety

Pool and spa chemicals can be hazardous. Follow the label, store products in their original containers, never mix different chemicals together and add chemicals to water, not water to chemicals. Wear the protection the label calls for and keep chemicals away from children and pets. If someone is exposed, call Poison Help at 1-800-222-1222 in the United States, or 911 in an emergency.

Doses are estimates

Dosing figures are rule-of-thumb rates scaled to your volume. Your water, your products and your conditions differ, so test your water before and after you add anything and follow the instructions on the product you are using.

Electrical work

The hot tub breaker and wire size calculator is a planning aid. Electrical work near water is dangerous and governed by local code, and it should be done or checked by a licensed electrician, who will account for your exact equipment, distance and local rules.

Structural loads

The hot tub pad weight calculator estimates the weight of the water, the tub and the people in it. It does not tell you whether a deck, slab or patio can carry that load. Ask the hot tub manufacturer and a qualified contractor or engineer.

Costs and equipment

Pool cost ranges, running costs and heater and pump sizes are planning figures. Quotes from local builders and the equipment maker’s sizing guidance should decide a purchase.

No warranty

We work to keep PoolCareCalcs accurate and up to date, but we make no warranty about accuracy, completeness or fitness for a particular purpose, and we are not responsible for decisions made using a result. If you find a mistake, please tell us through the Report an Issue form.
