Fiberglass tub with conical walls provides a wonderful experience, imagine sitting in a tub that is adjusted to your body shape. This model is very luxurious, as you can choose either thermo-wood or oak and a wide round edge is included in the offer already. This model requires less water, as the benches are closed and a pair of seats are a little bit higher. Walls and bottom insulation will keep the water warm for a longer time. What a consumer-friendly offer as you will use less wood and save money in the long term. If you want to place the heater somewhere further and not under the tub, feel free to order a tub with an external heater.
