Bathroom Renovation for IP

We are going to be renovating the bathroom in a recently purchased IP in Kallangur and would like some input on the proposed layout. It's 3/1/1 with the current toilet located next to the laundry, and bathroom consisting of a shower/vanity/bath.
Current layout and proposed layout attached, as well as a photo of it's current state. A few questions we're debating:
- is a large shower better than a shower over bath?
- 750mm vanity okay for a main (only) bathroom?
- what's a comfortable width for a toilet between a wall and a vanity?
Just occurred to me that we may have to swap the vanity and toilet around to ensure the door can open in case of emergency..
Any thoughts or comments would be appreciated!

 

Will removing bathtub cause issue with tenat with young family?
Considering cost to change plumbing around, can't you keep vanity position as it is, walk in shower next to it (instead of bath) and change current shower space to toilet?

 

Thanks @wylie . Door could be made a slider against the inside wall of the bathroom, would just have to mount the toilet roll holder on the vanity. Could potentially turn it into an outward opening door as well.

If I lock in the 750 vanity, the difference will be shared between the shower and toilet. As long as the toilet is usable and comfortable, I think the balance of space should be in the shower so it's as open as possible. This would also mean young families can place a tub in there for young children etc if they desired.

Did consider keeping the tub and putting a shower over, however it's not a big tub as it is and I think it would be a bit awkward to use as a shower. From a thread I read the other day someone suggested a large shower with removable shower head to allow for young children etc. Also if the shower is large enough they should be able to place a tub in there if required.
It's a wooden floor with ~700mm access so I'm not overly concerned about moving things around. We will probably swap the old copper pipes to poly as well, so might as well get the layout right now.
Walk in shower next to the current vanity location could work well though.

 

True, in general I dislike shower over bath for daily use. Was told that removing then will impact the marketability of one of the house so I decided against it.

If you reduce the vanity to 600mm, i think it will still be big enough and allow a bit more space for shower and toilet

I change my layout as attached, keeping toilet separate on the other room

 

I was told removing a bath takes away appeal too. Only two of my properties have a bath, the other 2 are showers only.

Haven't experienced any issues... at least that I am aware of anyway

I had a similar bathroom (you can't see the shower, but it's in the same position as yours)
I changed it to a very similar layout

I used a 750mm wide vanity, but with a shallow cabinet (otherwise it would have been too bulky).

Bathroom was about 1.6m wide too.

I went with a swinging door over a sliding door.
Sliding door would have meant cavity unless i used a hanging sliding door and that didn't work well as I was tiling floor to ceiling.

Generally toilets are about 600-650mm deep. So when sitting, that leaves about 250-300mm for knee space before getting smacked by a door. Close couple toilets have the most shallow depth (short of going in wall cavity units - too expensive and maintenance worries me to use them).

 

That was probably me.
Shower is so much quicker than bath.
They get a bath in one of those round tubs i picked up from bunnings/masters.

 

Floor plan of toilet
No dimensions though...
Builder also decided to swap the window out for a smaller one because for two reasons
1. Privacy
2. Water splashing onto the window sill and causing issues later.

 

True. Mine are in Sydney (15-20km from CBD), so I do have more variety of people coming in.

 

Thanks all for the replies. I suppose my options are:
1) Keep existing configuration of single separate toilet and shower/bath/vanity in bathroom
2) Additional toilet in bathroom with shower over bath
3) Additional toilet in bathroom with large shower and no bath

I will speak with a few local PM's and decide from there. Will post an after picture when done in the New Year.

This is a floor plan of my IP.

The bathroom and toilet are separate too.
Bathroom is 1.8m x 1.8m.

Given the norm/expectation these days is 2 toilets, I reconfigured the bathroom from a vanity + tub (shower over tub) into a vanity, toilet and 800x1000mm shower. I also kept the existing toilet. This way I have 2 toilets + 1 shower.

Note: The before image i posted earlier is of a different property.
