Tile Redi RN1620S-BI Redi Niche Single Recessed Shower Shelf - Ready

In this review of the Tile Redi RN1620S-BI Redi Niche Single Recessed Shower Shelf, the bottom line is simple: it is a practical, no-frills solution for homeowners and installers who want built-in shower storage that is waterproof and ready to customize. This single recessed niche with one inner shelf is best for new construction or remodels where a single, durable storage pocket is needed; the biggest reason to buy is that it installs quickly, fits standard stud layouts, and accepts tile directly so the finished look matches the shower surround.

Key Features

• All-in-one storage solution: A one-piece recessed niche with a built-in shelf gives a neat, integrated place to store soaps, shampoos and razors without extra hardware.
• Flexible orientation: The niche can be installed horizontally or vertically so installers can choose the best layout for bottle size and shower configuration.
• Ready to tile surface: Tile, marble or stone can be installed directly on the niche surface to achieve a customized, cohesive look with the rest of the shower.
• Waterproof construction: Made of high-quality plastic designed to be 100% waterproof and leak-proof, protecting the wall cavity and simplifying waterproofing details.
• Generous capacity: At 16 in width by 20 in height and 4 in depth, the niche fits multiple large bottles and keeps essentials organized.

Who It's For

The Redi Niche RN1620S-BI is ideal for contractors, DIYers and homeowners doing new showers or renovations who want a durable recessed shelf that is quick to install and easy to finish with tile. Its size suits standard showers where built-in storage for several bottles is desired and it works well on 16 in center studs as customers reported.

It is less appropriate for projects that require metal studs, extremely shallow wall cavities, or an integrated lighting or accessory module; those users should consider niche systems designed for those specific details. Also, if a painted-inset look is preferred without tile, buyers should confirm finish options before purchase.

Pros & Cons

Pros

• Easy installation in typical stud layouts, saving time on new construction or remodels.
• Durable, heavy-duty plastic construction that is waterproof and prevents leaks when installed correctly.
• Accepts tile directly for a seamless, customized appearance that matches the shower surround.
• Size and shelf depth accommodate multiple large bottles, eliminating the need for hanging caddies.

Cons

• One realistic limitation is that customization beyond tile (for example built-in lighting or specialty accessories) requires additional work not provided by the unit.
• The unit is a fixed-depth plastic shelf, so projects needing unusual cavity depths should verify fit before ordering.
