RV Outdoor Shower Exterior Shower Box Kit for RV - High Pressure

Our review of this RV outdoor shower exterior shower box kit finds it best suited for RV, camper and boat owners who want a straightforward replacement exterior shower that balances pressure and water savings. The single biggest reason to buy is the upgraded handheld head and extended hose, which deliver a noticeably stronger spray while reducing water use compared with standard 2.5 GPM heads. The kit is a simple, plastic-bodied exterior box with a keyed access, sized for a common cutout and designed for quick swap-in installation on travel trailers, motorhomes and vans.

Key Features

• Bigger shower head: The larger head and water saving switch give a higher-pressure shower experience while helping conserve onboard water.
• Variable flow: Water flow ranges from 0.35 to 1.75 GPM which lets users choose a gentle rinse or a stronger spray to stretch tank capacity.
• Long flexible hose: The included 68 in nylon hose extends reach around the exterior and is durable for routine outdoor use.
• Compact exterior box: The box measures 13.4 in x 8.45 in x 3.95 in and fits a mounting cutout of 11 in x 6 in for a straightforward replacement installation.
• Standard connection: Uses a 1/2 in-14 NPS connection making it compatible with common RV plumbing fittings.
• Durable construction: Made from premium synthetic resin to resist the elements and provide a lightweight, corrosion-free enclosure.

Who It's For

This exterior shower kit is aimed at RV and camper owners who need a direct replacement or upgrade to their outside shower that improves water efficiency without compromising pressure. It suits owners of travel trailers, motorhomes, vans and small boats who want an easy install using familiar 1/2 in-14 NPS fittings and a keyed box for secure exterior access.

It is less appropriate for users who require metal fixtures or who have specialized shower heads with unique fittings; also anyone needing a completely sealed, heavy-duty marine stainless solution should consider alternatives rather than this synthetic-resin kit.
