Urinal Grab Bar Sizes: 600mm and 627.2mm Rails, Ø27mm or Ø32mm Tube

Updated 2026-11-05 · RAYEN 雷茵

What is a urinal grab bar?

It is a frame of tube around a wall-hung urinal. It gives a user something to hold on both sides, and something to lean on in front. You see it in public washrooms, stations and care buildings. It is one piece of bent tube on each side, joined across the top, so the user is not reaching for two separate bars.

Our product photographs show these rails around urinals. Other grab bars in the range are straight or L-shaped and go beside a toilet. Do not swap one for the other without checking the shape: the frame form is made to stand off the wall on both sides of the urinal.

What sizes are they?

• HB2118: width 600mm, height 500mm, split 200 / 300 at the fixing. Tube Ø32mm, rose Ø80mm, Satin stainless.
• HB2918: the same 600mm width and 500mm height, the same Ø80mm rose. Tube Ø27mm, Satin stainless. Its drawing shows raised grip sections along the tube.
• OASHB301: width 627.2mm, depth 563.6mm, tube Ø27.2mm, in Satin stainless or Matt black.
• OASHB2118: the frame form in Matt black. Ask us for its drawing before you plan the wall.

Before you compare widths, check on the drawing where each figure is measured from: the tube centres or the outside of the frame. The two 600mm rails share the same frame size, so you can change the tube without redrawing the wall plan. Confirm the rose positions on the drawing first.

Should the tube be Ø27mm or Ø32mm?

A Ø32mm tube is a fuller grip, and a Ø27mm tube is lighter in the hand and looks slimmer. Think about who holds it. Older users and users with weak grip often need a shape they can close their hand around, and that differs from person to person. Hold a sample before you decide.

Rules for grab bars differ by country and by building type. They can set the tube size, the clearance, the height and the position. Check your local rules before you fix a size, and get the height and position from your architect or your building code. Our fixed grab bar guide compares the tube sizes across the range.

What must the wall be?

A grab bar takes a person's weight, so the fixing matters as much as the bar.

• Fix only into solid masonry, or into backing built into the wall for this purpose.
• Do not fix to glass, a shower screen, a door, or a hollow lightweight partition.
• Plain plastic plugs in a hollow wall are not a fixing for a grab bar.
• Plan the wall before the tile goes on. Backing added later means taking the tile off.
• Choose anchors for your wall and have the installer confirm them. Anchors and wall type are outside what we can see from here.

A wall-hung urinal often has a thin duct or a boxed-in pipe behind it. Find out what sits behind each rose position before you commit.

What should you measure?

• The urinal width and how far it stands from the wall.
• The finished wall, tile included.
• The side clearance: walls, partitions and the next urinal.
• The height of the urinal lip from the finished floor.
• What is behind the wall at each rose.

A worked example: a row of urinals in a station washroom, spaced with partitions between them. Measure the clear width between partitions first. If it takes a 600mm frame with room for a hand on each side, start with HB2118 for its Ø32mm tube. If a slimmer look suits the design, HB2918 fits the same width. If the project wants Matt black, look at OASHB301 and check its 627.2mm width against that same gap. Then ask us for the drawing and read the projection from the wall against the urinal.

Do you make flip-up bars for the toilet too?

Yes. 4 flip-up models sit in the care grab bar range, including OASHB2600 in Matt black. Lengths, tube and plate sizes are confirmed against the drawing for each model.

What to write on the order

Give the model, the tube, the finish and the wall type. For example: Grab Bar, HB2118, stainless steel, Satin stainless, width 600mm, height 500mm, tube Ø32mm, for solid masonry wall. Quantities, price and delivery are confirmed per order. Send us your washroom plan and we will send the drawing back with the quote.
