Intex PureSpa Greystone Deluxe Review 2026: Hard Water Pick

Sep 27, 2026

In this intex purespa greystone deluxe review, the Intex PureSpa Greystone Deluxe is the tub to pick if your tap water runs hard. It ranks #8 of 9 in our inflatable hot tub roundup and carries the label "best for hard water areas" because of a built-in hard water treatment system that reduces mineral buildup. The numbers: $799.99, the highest price in the group, a 3.5-star average from 1,122 Amazon ratings, 6 seats, 170 air jets, and a square 77 by 77 by 28 inch frame. It suits owners in hard water regions who value a 1-year limited warranty, and it is not the tub for shoppers chasing the best score per dollar.

Day to day, the Intex PureSpa Greystone Deluxe runs on 120-volt corded electric power and pushes heated air bubbles through 170 air jets, the highest jet count in this roundup. Fiber-Tech beam construction keeps the polyvinyl chloride walls firm, which matters on a 6-seat spa that measures 77 inches long, 77 inches wide, and 28 inches high. Meanwhile, the high-density thermal-resistant foam cover locks in heat and limits loss, a detail that counts because inflatable spas cool quickly between soaks. Maintenance is simple too: the integrated control box takes S1 cartridge filters, and two come in the box. At 130.5 pounds, the empty spa is light enough for two adults to reposition, and the two included headrests plus the LED light make evening soaks comfortable.

On value, the Intex PureSpa Greystone Deluxe asks $799.99, more than any other inflatable hot tub in our guide, and its 3.5-star average from 1,122 Amazon ratings is the lowest of the nine. That said, no rival here treats hard water at all, so if calcium and lime are scaling your fixtures, this is the only tub that attacks the problem at the source and can extend spa life. Even so, shoppers who do not fight hard water get higher scores for less money elsewhere in the roundup. Buy it if you want 6 seats, 170 jets, two headrests, an LED light, and a square footprint that tucks into a corner patio. If your water is already soft, skip it and save the money.

Frequently asked questions

How many people does the Intex PureSpa Greystone Deluxe seat?
It is rated for 6 people, and the square frame measures 77 inches long, 77 inches wide, and 28 inches high. The listed capacity is 290 pounds, so it fits a small group of adults comfortably. In practice, inflatable spas feel roomiest with four adults plus kids.
Does the Intex PureSpa Greystone Deluxe really help with hard water?
Yes, it has a built-in hard water treatment system made to reduce harsh mineral buildup and extend the life of the spa. No other inflatable hot tub in our nine-tub roundup includes that feature. That is why it earns our best for hard water areas label despite the price.
How many jets does it have and what power does it need?
The Intex PureSpa Greystone Deluxe has 170 air jets, the highest count in this roundup, and it runs on 120-volt corded electric power. The specs list no special wiring, so it plugs into a standard household circuit. Heated air bubbles do the work rather than high-pressure water jets.
What filters does the Intex PureSpa Greystone Deluxe use?
It uses S1 type cartridge filters, and two come in the box with the spa. The integrated control box is designed for easy cartridge replacement, so changes are quick. Intex does not list a set replacement interval, so check the cartridge when water flow drops.
What warranty comes with the Intex PureSpa Greystone Deluxe?
Intex backs the PureSpa Greystone Deluxe with a 1-year limited warranty. At $799.99 it is the most expensive tub in our guide, so that coverage matters if the pump or liner fails. Keep the receipt and the UPC on file for any claim.
Is the Intex PureSpa Greystone Deluxe worth $799.99?
It is worth it if you live in a hard water area and want 6 seats with 170 jets, because no other tub in this guide treats minerals. Otherwise, its 3.5-star average from 1,122 Amazon ratings and high price make cheaper, higher-rated models the smarter buy.
