OS X app for tile layout

[iTurbo]

I'm looking for an application on OS X that will help me with tile layout to help me build tile shower enclosures and floors. Anybody got any ideas? I've searched and haven't been able to find anything.

I'm not interested in an iOS app. I need real screen real estate to help me with many projects.

Hi,

I'm not aware of any apps that might help you. I do know some people use Sketchup to help visualise building interiors. I've never used it myself, but it might be worth taking a look and seeing what you think.

If you don't find anything suitable then I'm a developer who's always looking for interesting projects. If your needs are fairly simple and I think I can sell enough copies of to make it worth my while then I might take a look. Can you explain what you'd need your ideal app to be able to do?
