FANGNISN 90 x 90 Hot Tub Pad vs RELXTIME Hot Tub Mat

Both are thin floor mats that sit under an inflatable hot tub, and neither is a structural base. The FANGNISN is the larger and better-rated of the two: 90 x 90 inches, felt top over a waterproof PE backing, and 4.3 stars from 108 ratings. The RELXTIME is a 77.2-inch EVA foam mat at 1/5 inch thick, rated 3.7 stars from 99 ratings, and sized to RELXTIME's own 4-6 person square and 2-4 person round tubs. Buy the FANGNISN for a big round or square tub and for water absorption; buy the RELXTIME only if you want a denser foam feel and your tub fits inside 77 inches.

• Choose the FANGNISN if your tub is up to 90 inches across, you want a felt surface that soaks up splashes, and you care about the higher owner rating.
• Choose the RELXTIME if your tub footprint fits within about 77 inches and you prefer a thicker EVA foam mat over a felt-and-PE sheet.
