Why this product
The PetSafe Drinkwell Stainless Steel is the version of the Drinkwell fountain that solves the real long-term hygiene complaint with plastic bowls: biofilm buildup. Plastic surfaces develop micro-scratches that bacteria colonize, and over months the reservoir starts to harbor a slimy film that is hard to fully remove. Stainless steel has no micro-scratches and can be fully disinfected.
The 128 oz capacity is the second reason to buy this. It is larger than the plastic Multi-Tier (100 oz) and twice the Original (50 oz). For a multi-cat home or a large dog, refills happen every 3 to 5 days instead of every 1 to 2.
The 360-degree access design is the practical layout choice. Multiple pets can drink at the same time without bumping heads, which matters in homes with several cats or a cat-and-dog combo that drink together.

What PetSafe claims
PetSafe claims 128 oz of capacity in the stainless steel reservoir. That matches actual fill volume measured to the recommended max line.
PetSafe claims the stainless steel surface resists biofilm. The chemistry backs this up, stainless steel has a smooth non-porous surface that does not develop the micro-scratches plastic does over time. Disinfection with vinegar or dish soap reaches every surface.
PetSafe claims 360-degree access for multiple pets. The bowl is circular and the water cascades from a central spout, which means any approach angle works.
PetSafe claims a replaceable activated carbon filter, the same cartridge as the rest of the Drinkwell line. Filter service life is 2 to 4 weeks.
PetSafe claims a submersible low-voltage pump. The pump runs quietly, and stainless reservoir construction does not amplify motor vibration the way some plastic shells can.
Who should buy the Stainless Steel Drinkwell
Buy this if your cat has chin acne or you have had biofilm complaints with plastic fountains. Stainless steel is the material upgrade that fixes both.
Buy this if you have multiple pets or a large dog and want a fountain that does not need daily refilling. The 128 oz capacity covers multi-pet households comfortably.
Buy this if you prioritize cleaning. Stainless wipes down completely and survives dishwasher cycles without degradation, plastic accumulates haze and discoloration over years.
Skip this if you have one small pet and a tight budget. The plastic Drinkwell Original at $49 covers basic needs.
Skip this if you frequently move the fountain or worry about dropping it. Stainless dents permanently where plastic flexes and recovers.
Skip this if your kitchen counter has a strict aesthetic and you prefer plastic colors. Stainless is silver only.
Hygiene and capacity
The stainless steel reservoir is the structural reason to buy this. Plastic fountains develop biofilm and discoloration over months of use, no matter how often you clean them. Stainless steel does not, which is why veterinary clinics and high-end boarding facilities use stainless bowls almost exclusively.
The 128 oz capacity is the second structural advantage. For a two-cat home, refills happen every 4 to 5 days. For a large dog, every 1 to 2 days. The combination of more water and less refilling makes the fountain a low-maintenance fixture rather than a daily chore.
Pump noise and water freshness
The pump is the same submersible unit used across the Drinkwell line, but the stainless reservoir does not resonate the way some plastic shells do. Owner reports show the Stainless Steel runs quieter than the Original and similar to the Multi-Tier.
The central cascade design aerates the water as it falls, which is the consumer-fountain hydration story PetSafe applies across the Drinkwell line. The aeration is real and water taste improves over a static bowl.
Filter and cleaning
The replaceable activated carbon filter is the same cartridge as the rest of the Drinkwell line. Service life is 2 to 4 weeks, and bulk filter packs keep per-filter cost predictable.
Cleaning is the strongest argument for stainless. Wipe the reservoir with vinegar or dish soap and every interior surface is reachable. Pump disassembly every 2 to 4 weeks is still required, this is true of every Drinkwell model.
Build and footprint
Construction is stainless steel reservoir with plastic base and motor housing. The unit is heavier than plastic Drinkwells and dents permanently if dropped, but in normal countertop use the build feels meaningfully more premium.
Value
At $79 the PetSafe Drinkwell Stainless Steel Pet Fountain is the right Pet Supplies in 2026.

Should you buy the PetSafe Drinkwell Stainless Steel Pet Fountain?
The PetSafe Drinkwell Stainless Steel Pet Fountain is the right hygienic upgrade over plastic fountains in 2026.

The 360-degree design lets multiple pets drink at once, and the replaceable carbon filter keeps water fresh. At $79 it sits at the same price point as plastic multi-tier alternatives, and the materials upgrade is worth it for owners with cats prone to chin acne or households focused on hygiene.
Frequently asked questions
Is the Stainless Steel Drinkwell worth $79 in 2026?+
Yes for owners who prioritize hygiene or have cats prone to chin acne. Stainless steel does not harbor biofilm the way plastic does, and the 128 oz capacity is genuinely large. If you do not have a hygiene preference and want max value, the plastic Drinkwell Original at $49 covers the basics.
Stainless vs plastic Drinkwell: which is right?+
Stainless resists biofilm staining and is easier to fully disinfect. Plastic is cheaper, lighter, and survives drops better. For cats prone to chin acne or households focused on hygiene, stainless wins. For most other owners the plastic versions are fine.
Why do cats develop chin acne from plastic bowls?+
Plastic surfaces harbor biofilm in micro-scratches that bacteria use as a base. Repeated contact between a cat's chin and the contaminated rim can trigger acne. Stainless steel has no such micro-scratches and is easier to fully disinfect.
How loud is the pump?+
Quiet. The pump runs at a level that does not disturb most pets, and the stainless reservoir does not amplify pump vibration the way plastic can in older models.
Does it use the same filter as other Drinkwell models?+
Yes. The Stainless Steel uses the same replaceable activated carbon filter as the Drinkwell Original, Mini, and Multi-Tier. Bulk filter packs are widely available.
