Another method sometimes used is to coat the entire wall with 3/4″ plywood under the rock slab. Then grab bars could be mounted anywhere on that wall. 608.3 Handholds – Handholds must conform to Standard 609 and be provided in accordance with section 608.3. When multiple handholds are used, the required horizontal handles must be placed at the same height above the surface floor. According to ADA standards, grab bars are required in all accessible washrooms. Circular section handholds must have an outside diameter of 1.25 to 2 inches. Handholds with non-circular cross-sections (oval or rectangle) must have a cross-section not exceeding 2 inches in diameter and 4 inches around (circumference). The accessory must be free of sharp or abrasive elements, must not rotate and must withstand a force of at least 250 pounds. In summary, blocking is a critical element for security and installation. It must be sized and detailed on technical drawings with clear cross-references to architectures to ensure coordination and avoid errors. And the details differ depending on whether they are wooden or steel frames. Documentation of stock status during rough supervision is also very useful for trades and subsequent inspectors.
It should consist of photos with a sketch showing the size and center line of the blocking AFF, avoiding guesswork and assumptions. All this is very technical, but very important for the safety of life. This shouldn`t be left to the rules of thumb – avoid the perfect storm where assumptions can lead to under-anchoring grip handles. Wheelchair showers with seats require one or more grab bars at the rear and on the side walls opposite the seat, but cannot be installed above the seat itself. If there are no seats, grab bars must be present on all three walls, no more than 6 inches from the walls perpendicular to them. Wheelchair-accessible alternative showers require grab bars at the back and side walls furthest from the shower entrance, even at intervals of 6 inches from adjacent walls. Control. Controls other than drain plugs shall be mounted on a bulkhead. The controls are located between the edge of the tub and the handle and between the open side of the tub and the midline of the bathtub width.
The controls shall comply with section 309.4. A summary of the handrail requirements can be found in the following text and video. We always recommend calling or emailing an accredited CASp if you are unsure of your dimensions and need advice. Even the slightest miscalculation can result in an ADA lawsuit.

In showers and toilets, the top of a horizontal handrail should be 33 to 36 inches above the floor. The bottom of a vertical bar in transfer showers should be 3 to 6 inches above the horizontal bar on the wall. When I asked in the field what the blocking standard was, I heard that a rule of thumb for a 2×6 is centered on ±36″ AFF. The design for accessibility is special and an installation tolerance must also be specified. Since the blockage is hidden in the wall, it is extremely important to provide a number of installation heights for the grab bars that the block can accommodate. Another consideration is that grab bars are usually installed after completion, while in residential buildings they are installed in residential units on demand, which can be many years later.
So, is a 2×6 enough and in what amount? The size, length and location of grab bars are now universal for toilet stalls and individual bathrooms according to the ADA. Bathtubs without fixed seats should also have back and steering handles. Rear wall bars should be the same height as bathtubs with fixed seats, but they should be at least 24 inches long. One end of the bars must be 24 inches or less from the wall of the end of the head, while the other end must be 12 inches or less from the control end wall. In addition to these rods, gripper handles for the network head and control end walls are also required. The control end wall should have a bar of 24 inches or more on the front edge of the tub, while the headboard should be installed in the same position and should be at least 12 inches. A shower may need to have a shorter bar. The 2009 Code requires that all accessible showers be equipped with shower seats and that grab bars cannot be installed above shower seats. There are some exceptions to these restrictions. For bathrooms intended for the use of an individual (not for public or general use), it is not necessary to install grab bars. However, the walls still need to have the support structure to continue installing grab handles in the future if necessary. In addition, prisons with cells specially equipped to prevent suicide attempts do not need grab bars.

Although not mandatory, this accessory is recommended in all women`s toilet compartments. Disposal containers should be accessible from a seated position to be considered accessible and should be mounted under grab bars. Restraint rack requirements vary for bathtubs with and without a fixed seat, although they follow many of the same basic rules as toilet grab bars. ADA washroom requirements state that fixtures protruding from the wall or partition must not interfere with manoeuvring spaces or access to the handrail. To do this, the requirement is that accessories with projections must be mounted at least 12 inches above the top of the handrail or 1.5 inches below and to the side of the handrail. Accessories embedded in the sidewall or partition can be on the order of 12 inches above the handrail, but they can only project 1/4 inch. The openings (or exits) of all specialty accessories, with the exception of toilet paper dispensers, should be 18 to 48 inches above the finished floor.
Grab bars are one of many factors in ADA-approved bathroom design, including wheelchair access to sinks, minimum space requirements for wheelchair users to maneuver easily, and the proper height of sinks, toilet paper dispensers, and other items. In general, for a company with 25 employees or less, there should be at least one ADA-compliant cubicle in both bathrooms. When a building is constructed or renovated to some extent, bathrooms must be updated to be accessible to the ADA. Some problems can be attributed to the framing team. A blockage must be installed in the wall to secure the grip handles. Installers often place the lock in the wrong place or don`t think about it until it`s too late. For toilet stalls and showers, there is an obvious solution: the blockage must be confirmed by the contractor before installing the cement slab or drywall. Additional requirements for handrail In this example, there is also no tolerance for the installation height of the handles and the rods should only be limited to a diameter of 11/4″ to 11/2″. In addition, we need to know later exactly where the bar should be installed.
A 2×6 is therefore not suitable for locking and installing grab bars, as it does not offer the full range of installation heights and allowable bar sizes – this assembly is simply too demanding to be carried out in two stages by two different trades. I`ve also heard of rules of thumb for using a 2×8 or 2×10 or even 3/4″ textured plywood board on blocking.
