Moddy is software suitable for OTs and tech officers to design bathrooms.

Such as drop-down rails, horizontal rails, vertical rails and more
Every dimension calculated and labelled automatically
Crisp 2D and 3D plans for the NDIS, NHS and other funding bodies
Draw the existing bathroom, then duplicate it and modify. Before and after plans, done.
Include everything a builder or funder needs to see: door swing radius, grab rail sizes, shower niches, seats, walls and more — all auto-measured and labelled.
Trusted by OTs and technical officers worldwide to design safer, more accessible homes
Bathroom modifications are among the most common — and most scrutinised — reports OTs submit.
Moddy produces clear, dimensioned plans that funding bodies like the NDIS and NHS expect, so your workflows become easier and faster.
We allow occupational therapists to indicate various types of drains, including:
Center circular drains.
Wall-placed grill drains.
Corner-placed grill drains.
These are drawn using a circle or line tool. These options provide flexibility for different bathroom layouts and requirements.

We allow users to control and measure the following toilet dimensions:
This flexibility supports occupational therapists in specifying toilets based on individual anthropometric needs & brand specific dimensions.

An occupational therapist determines the appropriate seat height based on the measurement from the floor to the popliteal fossa (the back of the knee).
This ensures:
The required measurements depend on the scope of the bathroom modification:
For minor modifications (e.g., adding grab rails next to a toilet or shower):
For major modifications (e.g., extensive redesigns):
Key dimensions are critical for builders to translate the design into a functional and accurate renovation.
Moddy includes an auto-measurement feature for grab rails. This allows users to:
