Rimless or Rim Toilet Bowl: Flush Volume, Trap Size and Price

Fifteen of the 52 toilet bowls live on ThatRenoStore print 'rimless' on the listing, and nine of the fifteen are SANITON. Rimless starts at $330.00. A three-tick bowl flushing 3.5 litres starts at $160.00, and the trap printed on the listing decides which of them fits your floor.

The short version

Go rimless if you want the bowl design SANITON's listings say 'ensures easy cleaning': 15 live listings print it, from $330.00 for the ACACIA ST6019 bowl. If water use matters more, read the WELS block. Seven bowls print 3.5 litres full and 2.5 litres reduced flush at three ticks, and the SANITON CAMELLIA ST2488 is the lowest-priced of them at $160.00. Then match the trap to your floor.

SANITON's nine rimless listings all print a whirlpool flush; the bowl-only and full-set versions of BRASSICA, ACACIA and ALYSSA count separately. VERA prints 'Rimless Flush' in four one-piece titles, led by the VERA C.032 one-piece water closet at $599.00. Aalto prints 'Rimless Technology' on the ATH157 floor-mount and the AT2375 wall-mount. None of Baron's six bowls prints the word.

Rimless listings cluster in the middle of the range: 9 of the 15 sit between $400.00 and $599.99, and only the VERA C.032MB at $900.00 goes past $600.00. Every bowl under $250.00 is a model that does not print the word, 10 of the 12 of them SANITON.

Is a rimless toilet bowl worth the extra cost over a rim bowl?

The rimless floor here is $330.00, against $128.00 for the lowest-priced bowl that does not print the word. For the difference, SANITON's rimless listings print an anti-bacterial glaze, a whirlpool flush and a soft-closing urea seat, and the IXIA ST2466 carries all three at $410.00. In VERA's one-piece range the rimless C.032 and the tornado-flush C.083 are the same price, $599.00.

Which rimless toilet bowls cost under $400?

Five do: the SANITON ACACIA ST6019 bowl at $330.00, MORAEA ST2462 at $340.00, ALYSSA ST2611 bowl at $361.00, BRASSICA ST6011 bowl at $377.00 and the Aalto ATH157 at $396.00. The MORAEA is the one of the five that prints an S-trap, at 150 and 250mm.

Seven bowls print 3.5 litres at three ticks, from $160.00

21 of the 52 live toilet bowl listings print both a WELS tick rating and full and reduced flush litres, censused 01-10-2026. 21 = 6 Baron + 15 SANITON; the other 31 (12 VERA, 9 Aalto, 10 SANITON) print no complete litre pair. Two-tier listings print both a 2-tick and a 3-tick specification.

For the lowest-priced three-tick bowl, the SANITON CAMELLIA ST2488 at $160.00 prints 3.5 litres full and 2.5 litres reduced flush at three ticks, with S-trap set-outs of 140 and 250mm and a P-trap of 185mm. The SERISSA ST2966 at $170.00 and the CERINA ST2722 at $185.00 print the same litres. Baron's one 3.5 litre bowl is the BAW898 at $585.00; the other five Baron bowls print 3.8 or 4.0 litres at two ticks. Six of SANITON's nine rimless listings print the two-tier specification instead.

Which toilet bowls use 3.5 litres for a full flush?

Seven listings print 3.5 litres full and 2.5 litres reduced flush at three ticks: SANITON CAMELLIA ST2488 ($160.00), SERISSA ST2966 ($170.00), CERINA ST2722 ($185.00), MELISSA ST2452 ($230.00), JUNIOR ST2233 JW ($250.00), GARDENIA ST2234 ($320.00) and Baron BAW898 ($585.00), as at 01-10-2026.

Some listings also name the flush pattern. Aalto prints Double Vortex on the ATAL8090 and ATAL8050, VERA prints Tornado on the C.083 and A.032T, and SANITON prints Whirlpool on its rimless models.

Read the WELS block, then the flush litres, then the roughing-in

PUB's WELS scheme covers dual-flush toilet cisterns, so the tick rating is the first field to find. SANITON prints it as a 'PUB Water Efficiency Rating (MWELS)' block with the rating, the litres and the model code; Baron prints 'Water Efficiency' and 'Water Consumption' lines. On the two-tier listings, 3 ticks sits at 3.5 and 2.5 litres or less and 2 ticks at 4.0 and 3.0 litres or less.

The roughing-in comes next. 28 of the 52 listings print a set-out in millimetres, 11 different figures from 140mm to 300mm, and the S-trap or P-trap guide shows how to measure yours. The Aalto ATAL8090, for example, prints S-trap at 150mm or 250mm and P-trap at 180mm.

What does 'S-trap 150mm or 250mm' mean on a listing?

The bowl is offered for either S-trap set-out, 150mm or 250mm from the finished wall to the centre of the floor outlet, so you order the one that matches your measured outlet. The Aalto ATAL8090 prints S-trap 150 or 250mm and P-trap 180mm; the SANITON CAMELLIA ST2488 prints S-trap 140 or 250mm and P-trap 185mm.

The seat is the last line to read. 23 of the 52 bowls mention a seat: 17 name a urea seat, and the SANITON GAZANIA, DAISY and CANNA bowls name a PP soft-closing seat. The seat cover guide shows how to match a replacement to the bowl model.

One-piece bowls start at $299.00, two-piece at $291.00

Build printed Listings Lowest Highest
One-piece 15 $299.00 (VERA U.517, U.518) $900.00 (VERA C.032MB)
Two-piece or close-coupled 3 $291.00 (Aalto ATAL8020) $410.00 (SANITON MORAEA ST2462 Touchless)
Neither printed 34 $128.00 (SANITON LOTUS ST2322) $624.00 (VERA A.033)
Total 52 $128.00 $900.00

The same 52 live listings by the build each prints in its title or description, prices read 01-10-2026. 15 + 3 + 34 = 52.

A one-piece closet has the cistern and bowl moulded as one ceramic body; the VERA A.032T listing describes it as having 'no join between tank and pan to seal or wipe around'. A two-piece has a separate cistern on the bowl, as on Aalto's ATAL8050. For a rimless one-piece, the VERA C.305 at $479.00 is the lowest-priced, and the C.032 and C.093 are $599.00.

Do one-piece toilets cost more than two-piece?

On the listings that print the build, the one-piece range runs higher: $299.00 to $900.00 across 15 one-piece listings, against $291.00 to $410.00 across the three two-piece and close-coupled ones. In Aalto's range the ATAL8050 two-piece is $366.00 and the ATAL8090 one-piece is $516.00.
