How to convert bathroom to ensuite and separate bathroom?

Hello everyone,

I am looking for an opinion to renovate my shared bathroom to an ensuite + separate bathroom.

The door at the bottom goes to a master bedroom and sliding door on the right goes to walkway that goes to 2 other bedrooms and master bedroom.
Attached is the floorplan:

I am thinking to move the bathtub to accomodate a separate shower room.

Thank you in advance,

Sugi

Hi Sugi (@eegoos),

A warm welcome to the Bunnings Workshop community, it is wonderful to have you join us.

If you could provide some dimensions for the room, this would certainly help our members offer their best advice.

Is the idea to have two full bathrooms with showers, toilets and basins?

One with access from the hall, and one with exclusive access from the master bedroom?

If so, then I would remove the sliding door and the dividing wall between the WC and the bathroom, then add a dividing wall where I have marked below.

This would give you two rooms of roughly the same size that could have the full amenities installed without moving the window.

Allow me to tag @JoeAzza, @Nailbag and @Dave-1 to see if they have some ideas.

Let me know what you think.

I would also like to say "Hello" 🙂 and offer a warmwelcome to the Bunnings Community 🙂 Its a good place to belong to.

With the ensuite do you also want a toilet in there?

I do like @JacobZ 's roughout. It just depends on what services you wnat in both areas. Plus available space (waiting on dimensions as well)

Thank you @Dave-1 and @JacobZ for the response. I feel this forum is really alive and helpful for ideas.

The dimensions of the room is 1.8m wide x 2.8m long.

Is the idea to have two full bathrooms with showers, toilets and basins?
My initial idea was to have ensuite with showers, toilet and basin.

While the separate bathroom (in the new space, after divided) to have shower only.

In the separate toilet (the most top), would like to install small basin. 🙂

One with access from the hall, and one with exclusive access from the master bedroom?
yes, this is correct; new bathroom, access from the hall and one (bottom) exclusive acces from the master bedroom.

thank you so much for the roughout, I really like it.
I would like to keep the toilet and shower room (new) separately so they can get accessed any time.

thank you for looping in a great group of people!!

@Dave-1

Thank you Dave, really great to meet you here too.

Yes, I would like to have toilet in ensuite too.

I agree, I really like JacobZ roughout too. I am really grateful to get some ideas from everyone here.

My idea is to separate the shower (in new divided-space) with toilet, as mean they would have their own access door.

Thank you for the information. So space wise I think you can do it by loosing the bath, though it will be still be very tight.

From the ensuite door as you walk in.

Shower on your left. Next to it will be the toilet. Oppisite the toilet will be the sink either on the wall to the hall or better on the wall that backs onto the new bathroom area.

After the toilet there is a wall across seperating the two areas

You have a shower immediatly on the wall and then the toilet is where it is now. The sink is on the right hand side if you were sitting on the toilet. (backs onto the wall and the other side has the sink as well.

I am presuming a few things.

You have access to the outside of the house window side.

You under floor area is accessible.

You dont mind frosting the window as your toilet will back onto it. Or you could spin it so its on the middle wall. Just depends on your flooring space underneath. Window will still need to be frosted.

Your new toilet/bathroom will need more ventilation to take the humidity away.

Doorways are around 850mm ish, so your workable area has to encompass that, the 2.8m is that for the exoisting bathroom? the toilet area may be around the 950mm mark then. Which gives you just under 1.8m ish space per room.

thank you @Dave-1

yes, I get the idea.

yes, the outside of the house window side is roof.

the bathroom is on the 2nd floor.

yes, I don't mind frosting the window toilet, it is only a small window on the top.

yes, I agree, with the ventilation. definitely going to install exhaust fan.

yes 2.8m is for the existing bathroom.

yes toilet area is around 950mm (as I have 3x 30cm tiles visibible).

thanks again Dave, I really appreciate it.

Hello @eegoos

it’s great to see all the responses, one of my friends had her bathroom renovated, a real estate agent told her to keep the bath , it’s better for re sale in the future, especially if the buyer has small children.

you could split the rooms allowing for a small bath tub in place of the existing vanity, relocate the vanity and a toilet suite, where the bathtub was. In the other room install a small shower, with vanity and toilet ensuit, install doorways to suit your needs. Also note that installing cavity doors increases space.

The bathroom being on the second floor adds some complication to the plumbing especially for the waste.

I would have both toilets on the outside wall. Have a chat to a plumber as they will be able to give a better course of action in regaurds to the actual cheaper locations to have them. (I was thinking you were on the ground floor and had a cavity floor)

Hi @eegoos

Looking at the floor-plan your internal dimensions are around 1800mm wide x roughly 4200mm removing the dividing wall to the WC. I have two questions:

1. Are you on a slab or raised floor on stumps? Slab has complications and added expense on plumbing. Stumps is unlimited with minimal expense.

2. What are your "must haves" for the ensuite and bathroom? Unfortunately you can't simply position fixtures of any size just to suit the available space. There are minimum compliance requirements for spacings as well as usable functionality for toilets, showers, basins and tubs. These need to be complied to as a building permit will be required for this renovation. As an FYI renovating a bathroom without a permit will void insurance claims and possibly impact resale of the home. Not to be a spoiler here, but I see too many non-compliant bathroom renovations that come back to bite hard.

At first impressions, the relatively narrow rectangular total area is limiting options. A single combined 2-way ensuite/bathroom is worth considering as it will provide a far better functional space over attempted to reconfigure the existing into two without sacrifice.

Hi @Nailbag , thank you for your question.

This bathroom plan is on the 2nd floor so it will have a subfloor. I think it is similar setup with raised floor.

For mist-have,

I was thinking for ensuite are toilets, vanity and shower. But if space allowing, small bathtub is great too.

As for separate bathroom, only shower.

As for toilet, toilet and small basin.

Thank you for your concern, will try to get permit for it then.

Yes, I totally get your idea of just upgrading the single 2-way bathroom rather than converting to two.

The reason upgrading to two bathroom or three room (including toilet) is for easier access for everyone to take shower, as I only have 1bathroom 🙂

thanks again

Hi @eegoos

@JoeAzza makes an excellent point that losing the tub will have an impact on resale. That said, you have a more immediate requirement to have the area more useful to your lifestyle.

Your best solution will be to split the rooms into two and not 3 as the additional dividing wall will impact the usability of all 3 spaces.

You could consider a 2/3rds split with entry in the middle.

R1. The smaller room. 900 x 1200 shower and toilet with integrated vanity in the top of the cistern. Internal opening door with WC behind door

R2. 900 x 1200 shower with 1200 wide vanity. Cavity sliding door in middle.

2nd level rooms will allow for all plumbing changes to be both walls and floor internal.

Thanks for the suggestion @Nailbag

I’m trying to image the suggestion and ask a friend to draw it up.
is it something like this?

I’m thinking to have 900x1200 shower in ensuite.
is it possible ?

Hi @eegoos

I believe that is pretty close to what Nailbag was suggesting. Let me tag @Nailbag to make him aware of the drawing you've suggested.

Hi @eegoos

Great plans thank you.

Your plan indicates it's the bathroom having the larger shower not the ensuite. is that just a miss-label? Personally I would combine the single WC in to the middle bathroom. For the amount of time a bathroom is used vs a toilet and the extra space you will pick up is still the most effective use of space. However, the space works.

So, my only physical concern is the bottom (labelled Ens) 900mm x 900mm shower is too small for any door. You will loose a min 450mm on one side for the vanity and 600mm from the toilet. You could swap the vanity and shower. It will only give you a short vanity benchtop, but will allow for a larger shower with entry.
