Marlen In-Wall Shower System, Antique Brass Finish, Thermostatic Valve

Step into a shower where the temperature is already sorted before you turn the handle. The Marlen in-wall system pairs a solid brass mixer body, finished in a warm, aged antique-brass tone, with a concealed thermostatic valve, so the water settles at the level you set and holds there — no more mid-rinse surprises when someone runs a tap elsewhere in the house. Recessed mounting keeps the wall clean and uncluttered, letting the brass hardware read as the quiet detail it is meant to be, whether it sits inside a tiled bathroom or an outdoor shower enclosure.

Features

• Solid brass body — cast for real weight and long-term resistance to rust and corrosion, indoors or outdoors.
• Thermostatic safety valve — holds your chosen temperature steady for the whole shower, so you are not fighting sudden hot or cold surges.
• Standard-size fittings — a G 3/4" inlet and G 1/2" outlet sized to common plumbing, so it drops into most existing setups without special adapters.

Installation

The concealed valve is sized to line up with typical mounting spacing, so if you are replacing an older in-wall system the screw holes are often already in place, and the included instructions walk you through the rest. As with any concealed plumbing work, have a plumber handle the rough-in fitting if you are not already comfortable working behind the wall.

Where it fits

Built for shower or bathtub plumbing, and rated for indoor bathrooms as well as outdoor shower setups, so the same fixture works tucked into a tiled wall or mounted at a poolside rinse station.

Frequently asked questions

Can I install this outdoors?
Yes — the Marlen system is rated for both indoor bathroom and outdoor shower installations, and the solid brass body resists rust and corrosion in either setting.

Will it fit my existing plumbing?
It uses a G 3/4" inlet and G 1/2" outlet, both standard sizes, so it typically connects to existing shower plumbing without special adapters.

Does the water temperature stay steady?
Yes — the built-in thermostatic valve holds your chosen temperature for the whole shower, so it will not suddenly run hot or cold if pressure changes elsewhere in the house.
