We're happy to say The KUMO is designed to fit most standard US toilets.

Compatible

Non-Compatible

Standard Toilet

A standard toilet has a flat base, where it meets the toilet tank.

How to Check ? : Examine the toilet’s seat, it should be flat or have minimal curves from the front of the toilet tank base to the toilet holes(See figure 1).

(Figure 1.1)

(Figure 1.2)

Non-Compatible

French Curve Toilet

A French Curve toilet features a curvy base with flowing, sculpted contours where it meets the toilet tank base.

How to Check ? : Examine the front of the toilet tank base for a pronounced curve at the base of the toilet tank. If it has noticeable curve it’s likely a French Curve toilet (See figure 2).

(Figure 2.1)

(Figure 2.2)

2. Tank Accessibility

To bring The Health Arrow Bidet's to life, your toilet’s inlet valve must be accessible for our adapter to connect to.

Compatible

Non-Compatible

Visible water supply connection:

When the water supply hose (steel hose leading from the wall to your toilet) and the valve it connects to is visible on the outside of the tank, your tank is fully compatible!

How to Check: Look under or behind your toilet tank for a visible valve where the water supply hose attaches. (See Figure 3).

(Figure 3.1)

(Figure 3.2)

Non-Compatible

Non-Compatible Inlet Valves: Toilets with hidden or inaccessible inlet valves, such as flush-o-meter toilets(See figure 4) or some skirted toilets(See figure 5), where the valve is not exposed on the outside of the tank.

How to check?: look under or behind the toilet tank for a visible inlet valve. If the tank’s exterior is smooth, with no exposed valve or hose connection, or if you see a flush-o-meter, it’s likely non-compatible.

3. Hose Type

For a seamless fit a flexible hose is needed

Compatible

Non-Compatible

Flexible Hose

What It Looks Like: Flexible hose are bendable, braided stainless steel or plastic tube, connecting the inlet valve to the water supply valve.

How to Check: Locate the hose connected to the inlet valve under or behind your toilet tank. Gently wiggle it; it should feel flexible and move freely without resistance. (See Figure 6).

(Figure 6)

Non-Compatible

Rigid / Non-Flexible Hose

What It Looks Like: Ridged hoses are stiff, metallic (e.g., copper) or hard plastic (e.g., PVC) tube, typically straight or slightly bent, that feels solid and immovable. It lacks flexibility and cannot be easily adjustede.

How to Check: Find the water supply line connected to the inlet valve under or behind your toilet tank. Try to wiggle it; if it feels stiff, solid, or resists movement, it’s a rigid pipe and not compatible and must be replaced. (See Figure 7).

(Figure 7)

What to Do If You Have a Rigid Hose?

Visit your local hardware store and purchase a flexible hose that matches your toilet’s specifications. Unsure about the right hose size or need installation help? Contact our support team at support@TheHealthArrow.com.

Elongated Toilet

What It Looks Like: An elongated toilet bowl has an oval shape when viewed from above, with a longer front-to-back length (18.5 inches) compared to its width.

How to Check: Look at the bowl from above; it should appear oval, longer front-to-back than side-to-side. Measure from the center of the toilet holes (where the seat attaches) to the front rim; a distance of 18.5 inches confirms an elongated bowl. (See Figure 1).

(Figure 1)

Non-Compatible

Round Toilet

What It Looks Like: A round toilet bowl appears nearly circular or O shaped when viewed from above.

How to Check: Stand over the toilet and observe the bowl; it should look nearly circular. Measure from the center of the toilet holes(where the seat attaches) to the front rim; a distance of 16.5 inches confirms a round bowl.(See Figure 4).

Non-Compatible

Flexible Hose

What It Looks Like: a bendable, braided stainless steel or plastic tube, typically 12–24 inches long, connecting the inlet valve (at the base of the toilet tank or wall) to the water supply valve.

How to Check: Locate the hose connected to the inlet valve under or behind your toilet tank. Gently wiggle it; it should feel flexible and move freely. . (See Figure 8).

Rigid / Non-Flexible Hose

What It Looks Like: stiff, metallic (e.g., copper) or hard plastic (e.g., PVC) tube, typically straight or slightly bent, that feels solid and immovable.

How to Check: Find the water supply line connected to the inlet valve under or behind your toilet tank. Try to wiggle it; if it feels stiff, solid, or resists movement, it’s a rigid pipe and not compatible. (See Figure 9)

(Figure 9)

5. Required Space

Your toilet must have sufficient clearance between the toilet holes and the tank(95% of toilets have the space needed).

Compatible

Non-Compatible

Compatible Clearance: Toilets with at least 1.75 inches of clearance from the center of the toilet holes to the front of the toilet tank.

What It Looks Like: The space between the toilet holes (where the seat attaches) and the front edge of the tank is 1.75 inches or more. This allows the KUMO to sit flush.

How to Check: Use a measure measureing tape to measure from the center of the mounting holes to the front edge of the toilet tank. If the distance is 1.75 inches or greater, your toilet is compatible. (See Figure 10).

(Figure 10)

Non-Compatible

Non-Compatible Clearance: Toilets with less than 1.75 inches of clearance from the center of the mounting holes are not recommended.

What It Looks Like: The space between the mounting holes and the front of the tank is tight or cramped, less than 1.75 inches.

How to Check: Measure from the center of the mounting holes (between the bolts at the back of the bowl) to the front edge of the toilet tank. If the distance is less than 1.75 inches, your toilet is not compatible. (See Figure 11).

FAQ

Which bidet will fit a round toilet ?

Our MIZU FLOW bidet is the perfect match for round toilets, designed to fit flawlessly. Its sleek, non-electric design ensures a seamless and easy installation. Exciting news: we’re developing additional electric and non-electric models for round toilets, so stay tuned for updates!

Which bidet will fit a elongated toilet ?

Both our MIZU FLOW and KUMO bidets are engineered to fit elongated toilets perfectly, . These non-electric models offer superior comfort and hygiene with easy installation. Plus, we’re working on new pro and electric models for elongated toilets, launching soon!

What if my toilet has less than 1.75 inches of clearance between the mounting holes and the tank?

The MIZU FLOW requires minimal clearance, making it ideal for toilets with tight spaces, even less than 1.75 inches from the mounting holes to the tank (see Figure 5). The KUMO, however, needs at least 1.75 inches for a secure, flush fit. With less clearance, the KUMO may install but backward adjustments wont be able to be made.

My toilet has a skirted design with no visible inlet valve. Can I still use the Bidet Toilet Seat?

Unfortunately, our MIZU FLOW and KUMO bidets require an exposed inlet valve for connection with our brass T-adapter. Skirted toilets with hidden valves (see Figure 8) are not compatible, as we don’t currently offer skirted toilet bidet adapters.

I have a rigid pipe am I able to install the flexible hose myself ?

Absolutely! Replacing a rigid pipe (e.g., copper or PVC, see Figure 10) with a flexible hose is a simple DIY task. Turn off your water supply at the shut-off valve, unscrew the rigid pipe, and attach a flexible hose by screwing on two connections. It’s quick, requires basic tools. Need help selecting the right hose? Reach out to support@example.com

Do any of the bidets require electricity?

No power outlet needed! Both the MIZU FLOW and KUMO are non-electric, relying on water pressure for a refreshing, eco-friendly clean. They’re perfect for easy installation without electrical setup.
