I have a shower over bath combo' which its plastic resin something? It's a old bungalow and pitifully small. The amount of times I have nearly slipped over getting out, or lost my balance with soap in my eyes/ or after having a glass of wine. hate hate it. I did see a shower room with a additional hand held device and a over head shower. I thought that good for the odd squirt your feet down. The next owners will probably rip it all out and start again any way when design ideas change.

In situations like these, it depends what you normally use your laundry sink for. If you don't really need a 'laundry' tub as such, I usually recommend that my clients get a nice, comfortable and good-looking bathroom basin that they feel will suit their needs, and install a kitchen sink mixer, instead of a normal basin tap, so that the tap can be moved if you need to use the basin for larger items. Then add a hand towel ring and nice hand-soap dispenser and you have a dual purpose washing area. I always try to install washing machines and dryers in tower units, but not at the cost of benchspace - so it will really depend on the room layout (which I can't quite determine from your photos). Neat overhead storage is a must. Underbench pull-out clothes baskets and broom cabinets are always good, if you have the room. All the best!

Kazawa This bathroom has all the hallmark of a designer, if you have engaged a designer keep quality throughout, don't try to get the renovation on the cheap. Your designer has created a duct for services, modern plumbing is designed to last, the the majority of patented joining of copper pipes have a 25 year warranty. If you want perfection to last 25 yr +, Architects and quality bathroom renovations specify silver soldered ( brazed ) copper water pipes, and new pvc drainage pipes. It really is a case of you get what you pay. A plumber may take 8 hrs to rough in a bathroom with copper, silver soldered x $ 90/hr = $ 720 + materials= $ 1000 Or copper/ plastic with fittings $ 5 hrs x$ 90=$ 450 +materials $ 400 =$ 850 Only use taps/mixers with 15 year warranty e.g Grohe, Sussex, Methvan from $ 300e Bath steel Kaldewei Eurowa $ 400, 15 yr warranty A quality tiler will cost approx $ 3,000+-- Waterproofing , get it done professionally, to waterproof a bathroom exceeding Building Code of Aust usually takes 3 visits from waterproofer and will cost approx $ 1250 to $ 1500 with waterproofing certificate. and take 5 days, waterproofing is considered a structural component for home warranty insurance Only buy tiles from reputable tile shops, a tiler can only do his beat with quality tiles, if you give him rubbish tiles you get a poor job. Tilers in Sydney buy their less expensive tiles at Sefton A bathroom of the quality in the photo renovated properly/ professionally would set you back all up approx $ 30K + depending on vanity/ bench top, toilet suite Ken Evers Beach Bathrooms

It is looking lovely Nadia . I don’t believe that here is a right way as both are fine , but it is what suits you practically and visually . The smaller size basis give you two basins while leaving you plenty of bench space .
