Review: Oasis International R1P Remote Drinking Water Chiller: Stainless Steel
The Oasis R1P is our go-to choice for anyone who wants a steady supply of perfectly chilled water without having a big, bulky cooler taking up space. This chiller is compact enough to fit under most kitchen sinks, more on that later. Sure, its 1.0 GPH capacity means it's best for everyday use, grabbing a cold glass of water after working out in the garden or coming home from a long bike ride. It's a small luxury that most of the customers say they can't live without once they have had it. I have installed a few of these and generally they are straight forward. With the low flow rate, you will want to use a separate water dispenser at your sink, like an R.O. system. In fact, I think this pair with a reverse osmosis water filtration set up quite well.

Performance: 4.5/5 
The R1P absolutely gets the job done when it comes to keeping water cold. It nails its spec, chilling 1.0 GPH down to a refreshing 50°F in normal conditions. We love the adjustable thermostat because it lets you dial in the exact temperature you prefer. The recovery time is quick enough for most household use, so you're not waiting around to fill your glass, you get that satisfying cold glass every time.
User Experience: 5/5
Fitting this chiller under the sink is a breeze because it's so small. Plumbers and DIYers really appreciate the easy hookups: 1/4" OD stainless steel tube connections and I personally have not heard of anyone mentioning a leak on one of these units. For the DIY crowd, the installation is straightforward. The main thing to be aware of is the sound: when the compressor runs, you will hear it. It's just the nature of having an air-cooled unit tucked away, so plan for a little background hum.
Quality: 4/5 
This is where the R1P justifies its price tag. The fact that the entire waterway, including the storage tank, is all-stainless steel is a massive win. It ensures you get lead-free, clean water and guarantees the chiller won't rust out. It's built like a tank for long-term use. Oasis backs it with a one-year limited warranty, with a solid conditional extension often offered on the compressor, which speaks volumes about its construction. We have had a customer or two reach and mention that the unit has malfunctioned with in the year warranty and Oasis has taken the time to trouble shoot and take care of the customer.
Value: 3.5/5
Yes, this chiller is an investment—it costs more than some basic models. However, you're paying for premium features that count: all-stainless construction for water purity, a highly compact size, and reliable chilling performance. While the upfront cost is higher, the quality and longevity make it a great choice.
Final Verdict
The Oasis International R1P is the best compact chiller on the market for those who care about quality and convenience. If you want the cleanest possible water (perfect for pairing with an RO system!) and a unit that stays out of sight, this is the one to get.
Pro Tip: Give this little guy some breathing room in the cabinet! Good airflow prevents it from overheating, which means the compressor runs less often and for shorter periods, keeping things quieter. And don't forget to add a great filter, since this unit chills but doesn't purify the water.
Save Space & Add Chilled Water Anywhere
Install the R1P under a sink or near a non-refrigerated fountain to serve a bubbler, glass filler, or filtered tap with 1.0 GPH of cold water at point of use. The compact, air-cooled design eliminates the need for large, visible coolers.
Everyday Performance You Can Count On
Rated to deliver 50 °F water from 80 °F inlet at 90 °F ambient, the hermetically sealed refrigeration circuit with R-134a and an adjustable thermostat keeps temperature stable through typical draw patterns in homes and light commercial spaces.
Durable Materials, Cleaner Waterway
A stainless steel storage tank and all-stainless waterway resist corrosion and help maintain water quality, while welded water lines reduce leak points for long-term reliability.
Installer-Friendly Hookups
Standard 1/4″ OD stainless tube connections integrate with common point-of-use setups. A 4-foot power cord with a NEMA 5-15 plug simplifies electrical, and the small footprint fits comfortably in most base cabinets.
Sized Right For Tight Cabinets
Typical dimensions are about 12″ W × 11″ H × 10″ D, making routing of tubing and access to filters or shutoffs straightforward under standard sinks and counters.
Built To Code
The potable components are lead-free to NSF/ANSI 61 Annex G, and the unit carries UL listings for U.S./Canada with compliance to major plumbing codes for easy approvals.
Quiet, Adjustable Cooling
An adjustable thermostat (with OFF position) lets you fine-tune outlet temperature to your preference or service needs—handy for seasonal settings or pairing with filtration systems.
