Stainless Steel vs Plastic vs Ceramic Cat Water Fountains

By the PETME2 Team · Updated October 2026 · General information, not veterinary advice

Does the material of a cat water fountain matter?

Yes, it matters. Your cat drinks from the fountain every day, and you clean it every week. The material affects how easy it is to clean, how long the fountain lasts, how it looks in your home, and how much it costs. Here is how the three main options compare.

Stainless steel cat water fountains

Stainless steel is the same material used for many kitchen sinks and pet bowls. It is a popular pick for cat fountains for practical reasons.

Pros

• Very durable. It will not crack or shatter if your cat knocks it or you drop it while cleaning.
• Scratch resistant. The smooth surface stays smooth, which makes residue easier to wipe off.
• Easy to clean. Warm soapy water and a sponge are usually all you need.
• Modern look. Fits well in most kitchens and living spaces.

Cons

• Higher price than most plastic fountains.
• You cannot see through it, so you check the water level by looking inside.

Example: the PETME2 Stainless Steel Cat Water Fountain (3.2L / 108oz) has a large capacity, a 4-layer filter, an LED light, and a quiet pump. The bigger tank means fewer refills, which is handy in multi-cat homes.

Ceramic cat water fountains

Ceramic fountains look like pottery and come in many colors and shapes.

Pros

• Heavy and stable. Hard for a playful cat to tip over or push around.
• Smooth glazed surface that is easy to clean.
• Decor-friendly. Many people like the look.

Cons

• Breakable. A drop on a hard floor can chip or crack it.
• Heavy to carry to the sink for weekly cleaning.
• Chips in the glaze can be harder to keep clean.
• Often pricier, especially for larger sizes.

Plastic cat water fountains

Plastic fountains are the most common type. They are usually made from BPA-free plastic and come in many sizes and styles.

Pros

• Affordable. Usually the lowest price option.
• Lightweight and easy to carry and clean.
• See-through options let you check the water level at a glance.
• Lots of features, like low-water lights and different flow styles.

Cons

• Can scratch over time, and small scratches can trap residue. Use a soft sponge, not a scouring pad.
• Light, so a determined cat may be able to slide it around.
• Some owners simply prefer a metal or ceramic drinking surface.

Examples: the PETME2 Transparent 2.2L fountain lets you see the water level from across the room and uses a filter cartridge. The Classic 2L fountain is a simple, quiet option with a low-water light and anti-dry pump protection.

The middle ground: plastic body, stainless steel tray

Hybrid fountains use a plastic base with a stainless steel top tray where your cat drinks. You get a steel drinking surface at a lower price than an all-steel fountain. The PETME2 2.2L fountain with stainless steel tray is this style, with a 4-layer filter and a low-water light.

Side-by-side comparison

PETME2 fountains compared

Here is how the PETME2 range lines up by material and size:

What size cat water fountain do you need?

Choose a fountain that holds at least a full day of water for every pet that uses it. Material is only half the decision, so size matters too:

• One cat: a 2L to 2.2L fountain is usually plenty.
• Two or more pets, or long days away: a 3L+ tank means fewer refills.
• Cats and dogs sharing: pick a larger, sturdier fountain. Stainless steel will not break if a dog bumps it.

A bigger tank means fewer top-ups, but it still needs a weekly clean. Size changes how often you refill, not how often you clean.

Which fountain material should you choose?

Choose stainless steel for durability and easy cleaning, ceramic for a heavy, decorative look, and plastic for the lowest price or a clear tank. These quick rules help:

• Clumsy or playful cat? Choose stainless steel. It will not break if knocked over.
• Multiple cats? Go for a bigger tank, like a 3L+ stainless model, so you refill less often.
• Want to see the water level? A transparent plastic fountain makes this easy.
• On a budget but want steel? Pick a plastic fountain with a stainless steel tray.
• Want quiet? Look for a fountain that lists a quiet pump, whatever the material.

Whatever you choose, regular cleaning matters more than material. See our cleaning guide for a simple weekly routine.

How do you clean a stainless steel cat water fountain?

Wash it about once a week with warm water, mild unscented soap and a soft sponge, then rinse and dry the steel. Stainless steel is one of the easiest materials to keep clean. Here is a simple weekly routine:

1. Unplug the fountain and pour out the old water.
2. Take it apart: cover, filter, pump and bowl.
3. Wash the steel parts with warm water, mild unscented dish soap and a soft sponge.
4. Avoid steel wool, gritty powders and bleach. They can scratch or dull the finish.
5. For white spots, wipe or soak with half white vinegar and half water, then rinse well.
6. Clean the pump and rinse the filter with plain water.
7. Dry the steel parts with a soft towel to prevent water spots.
8. Reassemble, refill to the max line, and plug it back in.

Dishwasher? Check your manual first. The PETME2 3.2L stainless steel fountain has dishwasher-safe detachable parts, but the pump and cable must always stay out. For the full routine, see our cat water fountain cleaning guide.

Cleaning ceramic and plastic fountains

Ceramic: wash with the same mild soap and a soft brush. For hard water stains, soak the bowl in half vinegar and half water, then scrub gently and rinse. Check for chips each time.

Plastic: use a soft sponge only and hot, soapy water, then rinse well. Avoid harsh chemicals unless your manual says they are safe. If parts stay stained or deeply scratched, it is time to replace them.

Is stainless steel worth the extra cost?

If you have a playful cat, several pets, or you simply want a fountain that lasts, it usually is. You are paying for a drinking surface that will not crack and stays smooth after years of scrubbing.

On a tighter budget? A plastic fountain with a stainless steel tray gives your cat a steel drinking surface for less. And a well-kept plastic fountain is still a fine choice, as long as you clean it gently.

Common mistakes when choosing a fountain material

Frequently asked questions

Is stainless steel better than plastic for a cat water fountain?

For most homes, yes. Stainless steel is more durable, resists scratches, and is easy to clean. Plastic is lighter and cheaper, and can be a good choice if you clean it gently and replace it when it gets worn.

Are stainless steel cat fountains hard to clean?

No. Stainless steel cat fountains are usually among the easiest to clean. Warm water, mild soap, and a soft sponge work well. The pump and filter still need regular care, like any fountain.

Is a ceramic or stainless steel cat fountain better?

Stainless steel is usually more practical, because it will not chip or crack if dropped. Both have smooth surfaces that clean well. Ceramic is heavier and more decorative, so it suits homes where looks matter most and the fountain is unlikely to be knocked.

Do stainless steel fountains still need a filter?

Yes. The material does not change how hair and debris get into the water. A filter helps catch them between cleanings and protects the pump.

How do I clean a stainless steel cat fountain?

Unplug it, take it apart, and wash the steel parts with warm water, mild unscented soap and a soft sponge. Clean the pump, rinse the filter, dry the steel with a towel, then refill. Do this about once a week.

How often should you clean a stainless steel cat fountain?

Clean a stainless steel cat fountain about once a week, the same as any other fountain. Top it up every day or two, and clean it every 3 to 5 days if several pets share it. The steel is easy to scrub, but the pump and filter still need regular care.

How do I remove hard water stains from a cat fountain?

Soak or wipe the affected parts with a mix of half white vinegar and half water for 15 to 30 minutes. Scrub gently with a soft brush, then rinse until there is no vinegar smell left.

Does a stainless steel cat fountain rust?

Good quality stainless steel is made to resist rust in everyday use. Help it stay that way by avoiding bleach and abrasive pads, and by rinsing and drying it after cleaning. White spots are usually mineral deposits that come off with diluted vinegar.

Are stainless steel fountain parts dishwasher safe?

Many stainless steel fountain parts can go in the dishwasher, but always check your manual first. The PETME2 3.2L stainless steel fountain has dishwasher-safe detachable parts. The pump and power cable must always stay out of the dishwasher.

Why do some owners avoid plastic cat fountains?

The main reason is that plastic scratches more easily over time, and fine scratches can be harder to clean. Plastic can still be a good, affordable choice if you clean it gently and replace worn parts. Clear plastic also lets you see the water level at a glance.

What should I look for in a cat water fountain?

Look for a fountain that is easy to take apart and clean, has a quiet pump, and holds enough water for all your pets for a day or more. A material you can scrub easily, filters that are easy to replace, and a low-water warning are also helpful.

Why does my cat keep knocking over the water fountain?

Some cats paw at moving water for fun, and light fountains are easy to bump or push. A heavier fountain, such as stainless steel or ceramic, is harder to tip over. A flat, stable spot in a calm corner and a mat underneath also help.

Can cats and dogs share a stainless steel water fountain?

Yes, many homes do. Choose a larger tank, such as a 3L+ model, and plan to clean it more often, since more pets means more hair and debris in the water.
