Bliss white Tankless back to wall rimless toilet

Bliss tankless back‑to‑wall toilet — product description with pressure guidance

Modern, space‑saving, and cistern‑free

The Bliss Tankless Back‑to‑Wall Toilet connects directly to the mains water supply, giving a sleek, minimalist look without a visible cistern. Its white ceramic finish and clean lines suit contemporary bathrooms and commercial‑style interiors. Because it’s back‑to‑wall, the pan sits flush to the wall, concealing pipework for a tidy, streamlined finish.

How it works

• Tankless design: water is drawn directly from the mains, so no cistern is needed.

• Flush feed: positioned at the lower rear of the pan for neat plumbing and efficient operation.

• Supplied seat: UF slim soft‑close seat for quiet, controlled closing and longer durability.

• Certification and warranty: CE certified and backed by a 10‑year warranty for long‑term confidence.

Important note on mains pressure suitability

Because the Bliss uses mains‑fed, tankless flushing, it relies on having adequate water pressure to operate well. This isn’t ideal for every home, so it’s worth checking before specifying or installing.

Best use cases

• New builds and renovations where the plumbing is designed around modern mains supply and you can confirm sufficient pressure and flow.
• Homes with medium to high mains pressure are the safest bet for consistent flush performance.

What to know about pressure

• Typical UK mains pressure for homes is commonly cited around 2–4 bar. That’s considered normal, and flow rates under about 10 L/min are often taken as low.    
• At medium pressure within that 2–4 bar range, a mains‑fed toilet like Bliss is more likely to work satisfactorily, assuming flow isn’t restricted and the installation is correct.

When it might not suit

• Properties with low mains pressure or limited flow (for example, older systems or where supply is weak) may experience weaker or inconsistent flushing.
• If pressure is borderline or unknown, it’s wise to test or verify the actual pressure and flow at the installation point before committing to a tankless pan.

Simple pre‑installation check

1. Measure or confirm mains pressure with a gauge or through a plumber; target around or above the typical normal range of 2–4 bar.
2. Ensure supply lines and fittings are sized and installed properly, without unnecessary restrictions, to maintain good flow.
3. If pressure is uncertain or low, discuss whether a different toilet type or a pressure‑boosting solution is appropriate rather than assuming mains feed will be adequate.
