Buying my parents a new bathroom

When I was growing up my parents were pretty generous with money, I never went without and if I wanted something and said please and thank you enough times I pretty much got it. Unfortunately my Dad’s business took a turn and my Mum became too ill to work so their finances have dipped somewhat in later life. My Dad is extremely proud and struggles to ask for help, although my wife and I are luckily in a position to give it. We are paying for their bathroom renovations in Melbourne, my Dad still claims this is unnecessary and their bathrooms are fine, but they are decrepit and need a fresh touch. I have found it is far easier to pay for certain services than to just give my dad money, he flat out refuses cash and if I transfer money into his account I find it back in mine within a day! Their bathrooms haven’t been touched in about 15 years so I figured this would a good way to help them out. I wanted to go all out for them so I got them a lovely big tub, a rainforest shower head and beautiful carved stone sinks. I tried to keep it a surprise but when the ‘bathroom renovations Brighton’ van pulled up the game was kind of given away. Although my Dad was reluctant to accept my help he was always extremely grateful when I forced it on him. I saw him excitedly chatting away to the bathroom renovators and tenderly stroking the new tiles. My Mum was also excited but couldn’t really understand my motivation behind helping them and told me I really don’t need to. I told her to save her reservations until she has taken a bath in her new tub and if she still wasn’t sure about it I would listen to her.
