SketchUp V-Ray Bathroom Modeling
In this SketchUp bathroom modeling lesson, you model a bathroom and get the scene ready for a V-Ray render. The series brings the bathroom 3D modeling and V-Ray render stages together in videos. In this article, we share tips that help during the modeling stage and the points you should watch out for.
A bathroom is a small space packed with detail. Wall tiles, sanitary ware, fixtures and cabinets all fit into a tight area. That is why modeling to accurate dimensions and keeping things organized makes the render stage much easier.

The first lesson in the series runs about ten minutes. You can move on to the other lessons from the playlist.
YouTubeBefore you start modeling
A good bathroom model starts with a good plan. First, pin down the bathroom’s dimensions. Then mark where the door, the window and the plumbing points go. Without this information, any layout you make will need constant fixing later. (The video is in Turkish; this guide walks through the key steps in English.)
Choose the products you will use in the model up front, too. For example, decide at the very start whether you will use a shower tray or a bathtub. That decision affects the whole bathroom layout.
SketchUp bathroom modeling steps
The general method has a few steps. You can follow the same order in your own project.
- Draw the walls: build the walls to the plan dimensions and the room height.
- Cut the openings: cut the door and window openings at the correct heights.
- Add the sanitary ware: place the washbasin, the toilet and the shower area.
- Build the cabinets and shelves: model the vanity cabinet and the niches.
- Finish the details: add the mirror, the faucet, the towel rail and the accessories.
Watch your dimensions
In a bathroom, even an error of a few centimeters stands out. So model each product close to its real size. For example, washbasins are usually mounted 80 to 90 cm above the floor. In shower areas, you need to leave enough width for comfortable use.
Don’t forget the circulation space either. The door swing and the clear space in front of the toilet decide whether the bathroom is usable. In short, a realistic model is one that would also work in real life.
Organizing components and groups
Keeping the model organized saves you a lot of time at the render stage. Make each product a separate group or component. Turn products you use more than once, such as identical spotlights, into components. That way, when you change one, the others change at the same time.
Also keep the tiled walls as a separate group, because you will assign different materials to these surfaces at the render stage. To improve your modeling habits in SketchUp, take a look at our 9 tips for better modeling article.
Thinking about materials while you model
Keep the materials in mind while you model. For example, if the wall gets tile up to half height and paint above it, draw that boundary as a separate face in the model. Then you can easily assign two different materials at the render stage.
In the same way, create separate groups for the vanity top, the cabinet doors and the shower glass. Then give each group a meaningful name. This small bit of order lets you see at once which surface you are working on when you apply materials. It also makes things easier when you want to reuse the model in another project.
Getting ready for the render stage
Once the model is done, it’s V-Ray’s turn. Before you render, though, check the model one more time. Fix reversed faces, clean up unnecessary edges and save the camera as a scene. We have also covered downloading and installing V-Ray for SketchUp separately on our YouTube channel.
You can move on to our V-Ray bathroom render series, where we cover the lighting and rendering side of the bathroom with voice narration. Our current V-Ray 5 tutorials are on the channel too. For those, see our V-Ray 5 course set.
Common mistakes in SketchUp bathroom modeling
The most common mistake is modeling without accounting for wall thickness. The interior dimensions then come out smaller than they really are. The second mistake is trying to model the tiles one by one. That makes the file heavy and wastes time. Instead, apply the tile texture as a material. Finally, rather than downloading every product from 3D Warehouse, model the simple ones yourself. For the official guides to SketchUp’s tools, visit the SketchUp Help Center.
Frequently asked questions
What order should I follow for SketchUp bathroom modeling?
First the walls and openings, then the sanitary ware, and the accessories last. This order cuts down on the need for corrections.
Should I model the tiles one by one?
No, applying the tile texture as a material is enough. You can bring out the joints with a bump map.
Why should I use components in a bathroom model?
When you use the same product more than once, a component keeps the file light. And when you change one, the others change at the same time.
