We use a Pahaque stand alone shower (these are also used as toilet setups). The 60 inch shower line attached to the hand wand required the stand alone to be very close to the electrical outlet. A workaround is to go to Lowes and purchase a 3/8x3/8x3/8 barbed brass Tee and 3/8x3/8 straight connector, and attach a 20 ft section of 3/8 ID nylon reinforced vinyl tubing.
I cut the stock 60 inch hose into 2 30 inch segments, inserted the Tee to reunite these two parts to then allow use of the stock shower wand for simple rinse jobs. The third port on the Tee goes to a MagmaFlo Quick Disconnect adapter. The male end of the adapter is attached to one end of the 20 ft vinyl tubing and the other end has a 3/8x3/8 straight barbed brass connector that fits into a second shower wand that I had ordered separately.
The MagmaFlo adapter is the type used on backpack hydration systems. The 1/4 inch barbed adapter fits into the 3/8 inch ID vinyl (20 ft section) by using a 1/4 inch ID 1 vinyl segment over the 1/4 OD inch adapter barb. I would prefer using a Quick Disconnect that had a 1/3 inch OD barb, but have yet to locate that adapter. When I want a shower, I get the coil of 20 ft vinyl hose with its shower head and push the male end of the adapter into the female end that is permanently attached to the center arm of the Tee. I can send a picture, if that would help.
