Bathtub CAD blocks in plan, elevation and section
Bathtub CAD blocks for bathrooms and hotel suites, 13 of them: corner baths, round and oval tubs, rectangular bath tubs from 3' 10" to 6' 1" (1.18 m to 1.85 m) long, a two-person bath and a drop-in tub shell in section. Each is drawn 1:1 in plan or in section and comes as DWG and DXF in meters and in inches, SVG and PNG; 13 also in front and side elevation, and 13 as a 3D model in STEP, OBJ, GLB, 3MF and STL. Counting each view and each 3D model on its own, the library holds 54 blocks.

About the bathtubs library
What is in the library
54 blocks of 4 kinds, every one drawn from a real piece at full size; the sizes below are the drawings' own, in feet and inches (switch units at the top of the page). By feature: 5 with a deck or rim flanges, 3 with a seat, ledge or steps, 2 with armrests or a headrest, 2 with a deck mixer, 2 with an offset drain or end overflow. The table gives the baths drawn in plan, length by width (the first column is the longer side); the two sections are on their own pages.

Rooms you can plan with them
Bathrooms, en-suites and spa rooms. A built-in bath stands against one to three walls on a frame with a front panel; a corner bath fills a corner and leaves the floor in front of it free; a round tub or a bath with a wide deck sits in a raised platform, often with steps. The rooms above are built from blocks of this library, at real size: the alcove bath 4' 11" × 2' 7" and the corner bath 5' 3" × 5' 3".
Planning numbers that work for most bathrooms: a standard alcove bath 60 in (1.52 m) long and 30 or 32 in (76 or 81 cm) wide, 14 to 16 in (36 to 41 cm) high, in an alcove 60 in wide; corner and drop-in baths 18 to 20 in (46 to 51 cm) high; at least 21 in (53 cm) of clear floor along the side you step in from, 30 in (76 cm) to step in comfortably; the faucet and the drain at the same end.
Questions
What size is a bathtub?
The 12 baths drawn in plan in this library measure 3' 9" to 6' 7" (1.15 m to 2.00 m) by 2' 2" to 6' 7" (65 cm to 2.00 m). A standard US alcove bath is 60 in (1.52 m) long and 30 or 32 in (76 or 81 cm) wide; larger baths run 66 to 72 in (1.68 to 1.83 m), and a two-person bath is about 72 in (1.83 m) long.
How high is a bathtub?
A standard alcove bath is 14 to 16 in (36 to 41 cm) high and holds about 12 in (30 cm) of water to the overflow; corner and drop-in baths are 18 to 20 in (46 to 51 cm) high, freestanding soaking tubs 22 to 30 in (56 to 76 cm). The 3D models of this library stand 15 in (38 cm) high for the rectangular baths and 20 in (51 cm) for the corner, round and deck baths; the drop-in shell is 12½ in (32 cm) deep, as drawn, and its flange rests on the deck.
How much room does a corner bath need?
A corner bath takes 54 to 66 in (1.37 to 1.68 m) along each of its two walls, its front curving into the room; leave at least 21 in (53 cm) of clear floor in front of it, 30 in (76 cm) to step in comfortably.
Do the blocks come in 3D?
Yes: all 13 come with a 3D model of the bath, with its bowl, seats and steps where the drawing has them, the waste and the overflow.
Can I use them in Revit, SketchUp or Blender?
Yes. The DWG and DXF blocks import into Revit, ArchiCAD, SketchUp and any CAD program as 2D linework. The 3D models come as OBJ and GLB for Blender, 3ds Max and Twinmotion; STEP for Fusion, SolidWorks and FreeCAD; STL and 3MF for 3D printing.
Are they free for commercial projects?
Yes. Every file is free for personal and commercial work, with no account and no watermark.
How designers use these blocks
- Bathroom plansPlace the plan blocks to lay out bathrooms and en-suites, and check the clear floor beside the bath and the door swing. They are drawn 1:1, so a bath that fits on the drawing fits the room.
- Sections and elevationsThe two sections of the drop-in shell for construction details of a bath set in a deck; 13 baths also come in front and side elevation, projected from their 3D, for wall elevations and tiling drawings.
- Plumbing and structureThe drain, the overflow and the deck mixers where the drawings put them: a first check of the waste route and of the floor that carries a full bath.
- Presentation drawingsSVG and PNG for rendered bathroom plans in Illustrator, Photoshop, Figma or Canva.
- BIM and other CAD programsThe DWG and DXF blocks import or link into Revit, ArchiCAD, Vectorworks, BricsCAD and SketchUp as 2D linework for plans and sections.
- 3D and scale models13 blocks have a 3D model: OBJ and GLB for Blender, 3ds Max, Twinmotion and Unity, STEP for Fusion, SolidWorks and FreeCAD, and 3MF or STL to print a bathroom at 1:20 or 1:50.
