The ThirtyThreeRooms x SHOSU DIY SPH can be put in your favorite inflatable!
We developed this item in close cooperation with our friends from ThirtyThreeRooms and Valentine did a tutorial on how to install it in your favorite toy.
We changed the valve to a dual-action one-way valve! So either you add pressure by putting in air or you can add temperature to the SPH by putting in warm water.
The sizes are ±20cm deep and the connecting rim of the DIY SPH has a width of 20cm.
To keep shipping cost as low as possible, we will use a third party that ships once a week for orders that contain just the DIY SPH. When you combine your DIY SPH order with other items, we ship as fast as possible.
