Bathroom Install- Shed

I want a shower n toilet (semi), installed in a shed that isn't hooked up with plumbing. There is a shell/ cubicle for both a shower and a toilet, (a shower system- floor and reem nozzel and an actual toilet were installed when shed was built), but the pipes, plumbing and boiler were never completed. I would probably need to install a stand alone tank as well. Can somebody come and take a look please. Cheers Amy
