ZOMOFEW 1/2″ Thickness 85IN Hot Tub Mat
If you plan on using your inflatable spa during colder months, the ZOMOFEW is arguably your best option. Unlike standard mats, this utilizes high-density EVA foam that is a full 1/2 inch thick.
Detailed Review
The standout feature of the ZOMOFEW mat is its thermal efficiency. We often discuss winter hot tubbing, and the biggest enemy is heat loss through the ground. This mat acts as a legitimate thermal break between the cold concrete and your spa.
The puzzle-piece interlocking system is secure, and the kit includes a specific small mat for the pump unit, which is a thoughtful addition that many competitors miss. The texture is double-sided and frosted to prevent the tub from sliding, even when wet.
Pros
- Superior insulation (1/2″ thick) reduces heating bills.
- Includes 16 floor tiles plus a pump pad.
- High density EVA is comfortable on the feet.
- Rot and mold resistant material.
Cons
- Higher price point than felt mats.
- Puzzle edges can trap dirt if placed directly on mud.
AFFLUENT 85″ 1/4″ Thick EVA Mat
The AFFLUENT mat strikes a perfect balance between protection and ease of assembly. It is slightly thinner than the ZOMOFEW but provides excellent waterproofing and oil resistance.
Detailed Review
This mat is designed specifically to smooth out rough surfaces. If you are setting up your 4-person inflatable hot tub on a wooden deck that has potential splinters or gaps, the AFFLUENT mat bridges those imperfections perfectly.
The water and oil-resistant nature of this pad makes cleanup incredibly easy—simply hose it down. It eliminates the need for permanent concrete pads, making it ideal for renters.
Pros
- Excellent protection against sharp objects (rocks/twigs).
- Water and oil resistant for easy cleaning.
- Generous 85-inch size fits most large tubs.
Cons
- Thinner (0.25″) than the ZOMOFEW option.
- Less insulation value for extreme winters.
Aoebwpwi 80×80 Inch Absorbent Felt Mat
Moving away from EVA foam, the Aoebwpwi mat uses a felt construction with a PVC backing. This is the ideal choice for “messy” splashers as it absorbs water rather than repelling it.
Detailed Review
If your primary concern is slipping on a wet deck when exiting the tub, this felt mat is superior. The felt surface absorbs splashed water instantly, keeping the surrounding area dry. This is crucial for safety, especially if children or elderly users are enjoying the spa.
While it doesn’t offer the same cushioning as the EVA foam mats, the PVC backing ensures it is tear-resistant and won’t slide around. Note that at 80 inches, it is slightly smaller, so ensure you check your tub dimensions. For example, if you have a larger model like the Coleman SaluSpa, measure the base first.
Pros
- Absorbs water to prevent slipping hazards.
- PVC bottom prevents tearing and sliding.
- Can be cut to size if needed.
- Very affordable price point.
Cons
- Minimal cushioning (not soft on the feet).
- Needs to be dried out in the sun to prevent odors.
GQFOWE 80″x80″ Reusable Pool Protector
The GQFOWE is another felt-based contender that emphasizes durability and reusability. It is specifically marketed for both pools and hot tubs, making it a versatile addition to your backyard.
Detailed Review
Similar to the Aoebwpwi, this mat focuses on floor protection. If you have a nice wooden deck or expensive patio pavers, the GQFOWE prevents the heavy vinyl of the hot tub from grinding dirt into your flooring.
It is highly foldable and easy to store when the season is over. This mat is also compatible with maintenance tasks—use it to place your tools on when performing routine maintenance to avoid losing small screws in the grass.
Pros
- High absorbency for splash protection.
- Easy to fold and store in winter.
- Protects wooden floors from moisture rot.
Cons
- Not suitable for machine washing.
- Does not provide thermal insulation from the ground.
FENXAM 80″ Square Felt Mat
The FENXAM mat rounds out our list with a strong focus on its PE (Polyethylene) coated bottom, which offers superior wear resistance compared to standard PVC.
Detailed Review
The PE coating on the bottom of the FENXAM mat is the highlight here. It is designed to resist cracking even after prolonged exposure to the elements. It creates a stable, non-slip foundation for your spa.
It effectively absorbs oil and water, which keeps your patio tidy. If you are worried about scum build-up inside the tub, remember to use scum absorbers, but for the outside, this mat handles the mess perfectly.
Buying Guide: How to Choose the Perfect Hot Tub Pad
Choosing between EVA foam and Felt mats can be confusing. Here is what you need to know to make the right decision for your setup.
1. Material: EVA Foam vs. Felt
EVA Foam (like ZOMOFEW & AFFLUENT): These are essentially interlocking puzzle tiles. They offer the best cushioning and insulation. If you are placing your tub on concrete, this is mandatory to prevent heat loss. It also makes the bottom of the tub feel soft to sit on.
Felt (like Aoebwpwi & FENXAM): These are thinner mats designed to protect the floor and absorb water. They do not offer insulation or cushioning. Choose these if you are placing the tub on a nice wooden deck and want to prevent water stains or slipping.
2. Thickness & Insulation
Thickness matters. A 1/4″ mat is fine for physical protection, but a 1/2″ mat (like the ZOMOFEW) will actually lower your electricity bill by insulating the heated water from the cold ground. For more on maintaining efficiency, check our guide on the best inflatable hot tubs of 2025.
3. Sizing
Most mats are 80″ to 85″. Always measure the footprint of your hot tub including the pump unit. The pump usually sticks out 12-18 inches from the side of the tub. You want the pump to sit on the mat as well to reduce vibration noise.
Frequently Asked Questions
Can I put my inflatable hot tub on grass?
Yes, but you absolutely need a thick pad. Grass retains moisture and can rot the bottom of your tub over time. Furthermore, grass can hide sharp rocks. We recommend using the ZOMOFEW 1/2″ mat if setting up on grass to provide a solid barrier.
How do I clean these mats?
EVA foam mats can be scrubbed with mild soap and water. Felt mats should be rinsed with a hose and hung to dry. Do not put them in a washing machine as it can damage the non-slip backing. For tips on cleaning the tub itself, see how to clean an inflatable hot tub.
Do these mats prevent noise?
EVA foam mats are excellent at dampening vibration noise from the pump. If your neighbors are complaining about the hum of your hot tub pump, placing a thick foam mat underneath the pump unit is a great solution.
