Rigid Eco Foam Hot Tubs | Portable Spas

Yes, rigid hot tubs are generally cheaper to run than inflatable models. Though they have a higher upfront cost, rigid hot tubs are better insulated, leading to lower energy consumption over time. With fewer maintenance requirements and more durable materials, they offer long-term savings on both energy bills and upkeep compared to inflatable hot tubs.

For example, an inflatable spa can use approximately 16 kWh daily, while a foam spa uses around 8 kWh daily.

In the USA, assuming an electricity rate of $0.15 per kWh, the daily cost is approximately:

• $1.20 per day for a foam spa (8 kWh x $0.15)
• $2.40 per day for an inflatable spa (16 kWh x $0.15)

These figures are based on testing in ambient temperatures of 20°C (68°F) during summer. Actual costs may vary depending on local electricity tariffs and conditions, so this serves as an average estimate only.

It is generally cheaper to leave a rigid hot tub on all the time because maintaining a constant water temperature uses less energy than reheating the water from cold each time. Turning the hot tub off frequently or drastically adjusting the temperature causes the heater to work harder, which increases energy consumption and running costs over time.

Can you put a rigid hot tub on paving slabs? Yes, you can place a rigid hot tub on paving slabs, but it’s essential to ensure that the slabs are laid on a stable, professionally built base. This base prevents shifting and helps distribute the weight of the hot tub evenly, keeping the pavers in place and maintaining proper drainage to avoid water pooling underneath.

Rigid hot tubs are generally not hard to upkeep, but they do require regular maintenance. Key tasks include checking the water chemistry weekly, cleaning the filter, and ensuring the water temperature is consistent. Regularly draining and refilling the hot tub every three to four months is also recommended to maintain water quality. With proper care, rigid hot tubs can provide a relaxing experience with minimal effort.

When placing a rigid hot tub, it’s essential to put something underneath it to ensure stability and protect the base. A solid, level surface such as a concrete pad, pavers, or a hot tub mat provides adequate support and helps prevent damage to the hot tub's bottom. Additionally, using a mat or tarp can protect the area from moisture and debris, promoting better drainage and reducing the risk of mold and mildew. Always ensure the area is clear of sharp objects before installation.
