Frequently Asked Questions
Will these tubs fit in a standard shower stall?
Most portable tubs are designed to fit into standard shower stalls that measure at least 30 by 30 inches. Measure your shower tray carefully before purchasing, as you need enough room for the tub base and the external support feet.
How do I keep the water warm during a long soak?
Choose a model with a thermal cover or a lid to trap heat inside. Using a cover is the most effective way to prevent heat dissipation and maintain a consistent temperature for the duration of your soak.
Is it difficult to drain the water?
It is quite simple if you use the included drainage hose. You should position the tub near a floor drain or shower drain to ensure the water flows out easily without creating a puddle in your bathroom.
Can I use these tubs if I live in an apartment?
These tubs are excellent for apartments because they provide a deep soak without requiring any plumbing renovations. Just be mindful of the water weight and ensure your floor is level to prevent any accidental tipping.
Are these tubs comfortable to sit in for long periods?
Many models feature a cushioned bottom or an inflatable seat for added comfort. If the floor feels too firm, you can always place a soft towel or a foam mat underneath the tub to improve your experience.
